A double-sided multi-segment hook embroidery method of goldfish tail fin

Abstract

A method for double-sided, multi-segmented, hook-and-stitch embroidery of goldfish tail fins, using a needle and two different colored threads, is employed. On the first side, the first thread is laid along the tail fin's spine path from the starting point towards the tail. Then, using the needle threaded with the second thread, a long stitch is made along the tail fin's spine path from the second side through the embroidery to the first side. Next, a short stitch is made on the first side to hook and connect with the first thread, creating a long, contrasting stitch on the first side that corresponds to the long stitch on the second side. Simultaneously, the short stitch is hidden within the embroidery on the first side, forming the first segment of the linear embroidery. This process is repeated along the tail fin's spine path to create the second, third, and even more segments, as well as a second layer of reverse embroidery on top of the first layer. Ultimately, all the embroidered tail fin spine lines and textures naturally blend with the embroidery background to form a double-sided, multi-colored goldfish tail fin.

Description

Technical Field

[0001] This invention belongs to the field of embroidery, and relates to double-sided different color embroidery, and in particular to a method for double-sided different color multi-segment hook embroidery of goldfish tail fin. Background Technology

[0002] my country's embroidery craft has a history of more than 2,000 years. Among them, Suzhou embroidery, Guangdong embroidery, Hunan embroidery and Sichuan embroidery are collectively known as the "Four Famous Embroideries" of China.

[0003] Embroidery is a craft technique that uses a needle to guide thread and stitches onto a fabric according to a pre-designed pattern, ultimately creating a decorative design through the embroidered stitches. The fabric used for embroidery is typically a soft, elastic textile. Previously, commonly used fabrics for embroidery included cloth, silk, satin, and gauze.

[0004] Double-sided embroidery, also known as two-sided stitch embroidery, is a unique type of embroidery. It involves embroidering patterns on both sides of the same piece of fabric during the same embroidery process.

[0005] Double-sided embroidery is further divided into ordinary double-sided embroidery, double-sided embroidery with different colors on both sides, double-sided embroidery with three different colors on both sides, and double-sided embroidery with completely different colors on both sides. Ordinary double-sided embroidery refers to embroidery with the same pattern and color on both sides. Double-sided embroidery with different colors on both sides refers to embroidery with different colors, stitches, and shapes on both sides, while double-sided embroidery with completely different colors on both sides refers to embroidery with completely different patterns, colors, and stitches on both sides.

[0006] Double-sided embroidery differs from single-sided embroidery. Single-sided embroidery only requires meticulous work on the front, disregarding the stitches on the back. Double-sided embroidery, however, demands identical work on both sides. Ordinary double-sided embroidery presents completely identical patterns and designs on both sides, with no distinction between front and back. In terms of technique, it doesn't embroider the front first and then the back; instead, it employs a skillful technique to complete the work in one go, ensuring both sides have meticulous stitches and threads, while also making sure every stitch is seamless and imperceptible.

[0007] In the field of embroidery, goldfish are a common subject due to their graceful form. The goldfish's tail fin plays a crucial role in controlling direction, providing propulsion, and maintaining balance. The tail fin typically consists of at least one lobe, which is formed by linear fin spines and plate-like fin plates. The shape of the goldfish tail fin varies greatly; a typical goldfish tail fin is forked. Furthermore, the tail fin's area is significantly larger and more prominent than the body, and its overall movement is soft and flowing, making it a key and challenging element in embroidery. According to the inventor, current embroidery techniques for goldfish tail fins typically only employ flat stitch or large random stitch for ordinary double-sided embroidery (with identical patterns and colors on both sides). Because the tail fin's lobe is composed of linear fin spines and plate-like fin plates, the pattern lines are sparse, thin, and cover a large area. Therefore, ordinary double-sided embroidery using flat stitch or large random stitch results in poor texture, lacks dynamism, and appears stiff, unnatural, and unattractive. According to search results, there are currently no double-sided embroidered products featuring different colors for goldfish tail fins.

[0008] In view of this, how to design an embroidery method that can satisfy the dual-color requirement and better express the special effect of the goldfish's tail fin is the research topic of this invention. Summary of the Invention

[0009] This invention provides a method for embroidering goldfish tail fins with double-sided, multi-segmented, hook-and-embroidery, which aims to solve the long-standing problem in the field of embroidery of poor texture effects or even the complete absence of double-sided, multi-colored embroidery on goldfish tail fins.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a method for double-sided, multi-segmented hook embroidery of goldfish tail fins, wherein an embroidery pattern containing a goldfish tail fin graphic is first made on a taut embroidery base, wherein the goldfish tail fin graphic in the embroidery pattern is mirrored on both sides of the embroidery base, and then a single embroidery needle and two threads of different colors are used to perform double-sided, multi-segmented hook embroidery of the goldfish tail fin graphic.

[0011] Define one of the two embroidery threads of different colors as the first embroidery thread and the other as the second embroidery thread.

[0012] Define the front side of the embroidery base material as the first side and the back side as the second side.

[0013] The goldfish tail fin pattern consists of at least one tail lobe, which is formed by alternating adjacent linear tail fin spines and plate-like tail fin plates. The double-sided heterochromatic embroidery is performed on each linear tail fin spine, and the double-sided heterochromatic embroidery lines on each linear tail fin spine are performed according to the following steps: Step 1: Preparing to start stitching Select a point on the linear tail fin barb as the starting point, and position or fix one end of the first embroidery thread and the second embroidery thread at the starting point. The first embroidery thread is located on one side of the first side of the embroidery base material, and the second embroidery thread is located on one side of the second side of the embroidery base material. The second embroidery thread is threaded onto the embroidery needle.

[0014] Step Two: First Layer of Forward Multi-Section Hook Embroidery The first step is to embroider the first layer of the embroidery, using a combination of long and short stitches on the first section. On the first surface, the first embroidery thread is laid from the starting point along the linear tail fin thorn path towards the back of the fish tail.

[0015] Then, on the second surface, starting from the starting point, the embroidery needle is placed along the linear tail fin piercing path towards the back of the fish tail at intervals to form the first needle eye of the first layer. The needle is then passed through the embroidery base material from the second surface to the first surface, and the second embroidery thread is pulled until the second embroidery thread forms the first long stitch of the first layer on the second surface.

[0016] Next, on the first surface, the position near the first needle eye of the first layer is used as the second needle eye of the first layer. The needle is then passed through the embroidery base material from the first surface to the second surface and pulled along the second embroidery thread until the second embroidery thread forms the first short stitch of the first layer on the first surface. This first short stitch, because it is connected to the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch of a different color correspond to the first long stitch of the first layer. At the same time, the first short stitch of the first layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0017] The second step involves embroidering the first layer of stitches, with a combination of long and short stitches on the second section, facing forward. Next, on the second surface, starting from the second eye of the first layer, follow the linear tail fin piercing path towards the back of the fish tail at intervals to form the third eye of the first layer. Pass the needle through the embroidery base material from the second surface to the first surface and pull the second embroidery thread until the second embroidery thread forms the second long stitch of the first layer on the second surface.

[0018] Next, on the first surface, the fourth needle eye of the first layer is located near the third needle eye of the first layer. The needle is then passed through the embroidery base material from the first surface to the second surface and pulled by the second embroidery thread until the second embroidery thread forms the second short stitch of the first layer on the first surface. This second short stitch, because it is connected to the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch of a different color correspond to the second long stitch of the first layer on the second surface. At the same time, the second short stitch of the first layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0019] The third step is to embroider the first layer of stitches, with the third section featuring a combination of long and short stitches. Next, on the second surface, starting from the fourth eye of the first layer, the embroidery needle is placed along the linear tail fin path towards the back of the fish tail at intervals to form the fifth eye of the first layer. It passes through the embroidery base material from the second surface to the first surface and pulls the second embroidery thread until the second embroidery thread forms the third long stitch of the first layer on the second surface.

[0020] Next, on the first surface, the position near the fifth eye of the first layer is used as the sixth eye of the first layer. The needle is then passed across the first embroidery thread and through the embroidery base to the second surface, pulling the second embroidery thread until the second embroidery thread forms the third short stitch of the first layer on the first surface. This third short stitch, because it crosses the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch of a different color correspond to the third long stitch of the first layer on the second surface. At the same time, the third short stitch of the first layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0021] Continue this process until the desired embroidery length is reached.

[0022] Step 3: Second layer: Reverse overlay multi-section hook embroidery Next, using the last needle hole from step two as the starting point for the second layer, and following the pattern of step two, reverse the process after completing the embroidery in step two: The first step is to embroider the second layer, reverse the first section of long and short stitches. On the first surface, lay the first embroidery thread from the last needle eye in step two along the linear tail fin thorn path toward the front of the fish tail.

[0023] Then, on the second surface, starting from the last needle hole in step two, follow the linear tail fin piercing path towards the front of the fish tail at intervals to form the first needle hole of the second layer. Pass the needle through the embroidery base material from the second surface to the first surface and pull the second embroidery thread until the second embroidery thread forms the first long stitch of the second layer on the second surface.

[0024] Next, on the first surface, the needle is placed near the first eye of the second layer as the second eye of the second layer. The needle is then passed through the embroidery base from the first surface to the second surface and pulled across the first embroidery thread. The second embroidery thread is pulled until it forms the first short stitch of the second layer on the first surface. This first short stitch, because it crosses the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch correspond to the first long stitch of the second layer on the second surface. At the same time, the first short stitch of the second layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0025] The second step is to embroider the second layer of reversed, second section of long and short stitches. Next, on the second surface, starting from the second eye of the second layer, follow the linear tail fin piercing path towards the front of the fish tail at intervals to form the third eye of the second layer. Pass the needle through the embroidery base material from the second surface to the first surface and pull the second embroidery thread until the second embroidery thread forms the second long stitch of the second layer on the second surface.

[0026] Next, on the first surface, the fourth needle eye of the second layer is located near the third needle eye of the second layer. The needle is then passed across the first embroidery thread and through the embroidery base to the second surface, pulling the second embroidery thread until it forms the second short stitch of the second layer on the first surface. This second short stitch, because it crosses the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch correspond to the second long stitch of the second layer on the second surface. At the same time, the second short stitch of the second layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0027] The third step is to embroider the second layer of the reverse third section with a combination of long and short stitches. Next, on the second surface, starting from the fourth eye of the second layer, the embroidery needle is moved along the linear tail fin path towards the front of the fish tail at intervals to form the fifth eye of the second layer. It passes through the embroidery base material from the second surface to the first surface and pulls the second embroidery thread until the second embroidery thread forms the third long stitch of the second layer on the second surface.

[0028] Next, on the first surface, the sixth needle eye of the second layer is located near the fifth needle eye of the second layer. The needle is then passed across the first embroidery thread and through the embroidery base to the second surface, pulling the second embroidery thread until it forms the third short stitch of the second layer on the first surface. This third short stitch, because it crosses the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch correspond to the third long stitch of the second layer on the second surface. At the same time, the third short stitch of the second layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0029] Continue this process until the predetermined embroidery length is reached. The length of the second layer of reverse multi-section stitches partially or completely covers the length of the first layer of forward multi-section stitches.

[0030] Step 4: Third layer: Front-facing multi-section hook embroidery Next, using the last needle hole in step three as the starting point for the third layer, continue the embroidery process in the forward direction following the pattern established in step three: The first step is to embroider the third layer of the first section with a combination of long and short stitches. On the first surface, lay the first embroidery thread from the last needle eye in step three along the linear tail fin thorn path toward the back of the fish tail.

[0031] Then, on the second surface, starting from the last needle hole in step three, follow the linear tail fin piercing path towards the back of the fish tail at intervals to form the first needle hole of the third layer. Pass the needle through the embroidery base material from the second surface to the first surface and pull the second embroidery thread until the second embroidery thread forms the first long stitch of the third layer on the second surface.

[0032] Next, on the first surface, the needle is placed near the first eye of the third layer as the second eye of the third layer. The needle is then passed across the first embroidery thread and through the embroidery base to the second surface. The second embroidery thread is pulled until it forms the first short stitch of the third layer on the first surface. This first short stitch, by passing across the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch correspond to the first long stitch of the third layer on the second surface. Meanwhile, the first short stitch of the third layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0033] The second step involves embroidering the third layer of the second section with a combination of long and short stitches. Next, on the second surface, starting from the second eye of the third layer, follow the linear tail fin piercing path towards the back of the fish tail at intervals to form the third eye of the third layer. Pass the needle through the embroidery base material from the second surface to the first surface and pull the second embroidery thread until the second embroidery thread forms the second long stitch of the third layer on the second surface.

[0034] Next, on the first surface, the fourth needle eye of the third layer is located near the third needle eye of the third layer. The needle is then passed across the first embroidery thread and through the embroidery base to the second surface. The second embroidery thread is pulled until it forms the second short stitch of the third layer on the first surface. This second short stitch, because it crosses the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. This long stitch of a different color corresponds to the second long stitch of the third layer on the second surface. At the same time, the second short stitch of the third layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0035] The third step is to embroider the third layer of the third section with a combination of long and short stitches. Next, on the second surface, starting from the fourth eye of the third layer, the embroidery needle is placed along the linear tail fin piercing path towards the back of the fish tail at intervals to form the fifth eye of the third layer. It passes through the embroidery base material from the second surface to the first surface and pulls the second embroidery thread until the second embroidery thread forms the third long stitch of the third layer on the second surface.

[0036] Next, on the first surface, the sixth needle eye of the third layer is located near the fifth needle eye of the third layer. The needle is then passed across the first embroidery thread and through the embroidery base to the second surface, pulling the second embroidery thread until the second embroidery thread forms the third short stitch of the third layer on the first surface. This third short stitch, because it crosses the first embroidery thread, sews the first embroidery thread on the first surface into a long stitch of a different color. The position and length of this long stitch of a different color correspond to the third long stitch of the third layer on the second surface. At the same time, the third short stitch of the third layer is hidden in the embroidery on the first surface because of its short and small stitch length.

[0037] Continue this process until the predetermined embroidery length is reached, where the length of the third layer of forward multi-section stitches partially or completely covers the length of the second layer of reverse multi-section stitches.

[0038] This process is repeated until each line of the goldfish tail fin is embroidered according to the goldfish tail fin pattern. Finally, all the embroidered lines of the tail fin are naturally combined with the embroidery base material in the goldfish tail fin pattern area to form a double-sided goldfish tail fin with different colors.

[0039] The relevant content in the above technical solution is explained as follows: 1. In the above solution, the "embroidery base material" refers to the embroidery material used in embroidery, also known as embroidery cloth, which is usually a soft, elastic textile fabric. In this invention, the embroidery base material can be a transparent, semi-transparent, or opaque fabric.

[0040] 2. In the above scheme, "needlework" refers to the method of needlework in embroidery, and also the organizational form of stitches in embroidery. "Stitch" refers to a single line of embroidery thread created between two needle holes.

[0041] 3. In the above scheme, "forward" refers to the direction from the goldfish's tail stalk towards the back of the tail. "Reverse" refers to the direction opposite to "forward".

[0042] 4. In the above scheme, the "line segment" in "the double-sided embroidered line segment on each linear caudal fin spine" refers to a line segment on a linear caudal fin spine. A linear caudal fin spine is usually made up of multiple "line segments".

[0043] 5. In the above scheme, in step one, positioning or fixing one end of the first embroidery thread at the starting point is done as follows: first, thread the embroidery needle through the first embroidery thread, then tie a knot at one end of the first embroidery thread, and then use the embroidery needle to pass through the embroidery base material from the second side to the first side at the starting point and pull the first embroidery thread until the knot is located on one side of the second side and the first embroidery thread is located on one side of the first side.

[0044] 6. In the above scheme, in step one, positioning or fixing one end of the second embroidery thread at the starting point is done as follows: first, thread the embroidery needle through the second embroidery thread, then tie a knot at one end of the second embroidery thread, and then use the embroidery needle to pass through the embroidery base material from the first side to the second side at the starting point and pull the second embroidery thread until the knot is located on one side of the first side and the second embroidery thread is located on one side of the second side.

[0045] 7. In the above scheme, in step one, the starting point is selected at one end of a linear tail fin spine near the goldfish's caudal peduncle.

[0046] 8. In the above scheme, in the embroidery of a linear tail fin on the same side, different or the same thread diameters are used for embroidery and combination for the same line segment.

[0047] 9. In the above scheme, in the embroidery of a linear tail fin spine on the same side, different or the same thread colors are used for embroidery and combination on the same line segment.

[0048] 10. In the above scheme, in the embroidery of a linear tail fin spine on the same side, different or the same thread diameter is used for embroidery and combination for different line segments.

[0049] 11. In the above scheme, in the embroidery of a linear tail fin spine on the same side, different or the same thread colors are used for embroidery and combination for different line segments.

[0050] 12. The above solution is applicable not only to hand embroidery but also to machine embroidery (mass production) in industrialized mass production. When using machine embroidery, all the stitches of this invention can be converted into points and sequences in planar coordinates, and then programmed for the embroidery machine to complete. Therefore, the technical solution of this invention possesses practical applicability under patent law.

[0051] The principle and effect of this invention: To solve the long-standing problem of poor texture effect, or even the complete absence of double-sided color embroidery, in the field of goldfish tail fin double-sided embroidery, this invention addresses the issue of goldfish tail fin patterns that are mirror images of each other on the same embroidery base. A single embroiderer can use one needle and two different colored threads, employing a multi-section hook embroidery method, to simultaneously perform double-sided color embroidery on both sides of the embroidery base. Specifically, on the first side, the first embroidery thread is laid from the starting point along the linear tail fin path towards the tail. Then, using a needle threaded with the second embroidery thread, a long stitch is used to pass from the second side through the embroidery base to the first side along the linear tail fin path. Next, a short stitch is used on the first side to hook across and connect with the first embroidery thread, creating a long, contrasting stitch on the first side that corresponds in position and length to the long stitch on the second side. Simultaneously, the short stitch, due to its short length and small size, is hidden within the embroidery on the first side, forming a linear embroidery pattern of combined long and short stitches in the first section. Following this pattern, the second, third, and even more sections of the linear tail fin are embroidered along the path of the embroidered spines. A second layer of reverse embroidery is then applied over the first layer, and so on, until all the embroidered linear tail fin spines naturally combine with the embroidery base material within the goldfish tail fin graphic area to form a double-sided, multi-colored embroidered goldfish tail fin. This invention solves the long-standing problem of poor texture effects or even the complete absence of double-sided multi-colored embroidery in the field of goldfish tail fin embroidery. In particular, the embroidered double-sided multi-colored goldfish tail fin has clear, realistic, natural, soft, smooth, and dynamic textures. Compared with existing embroidery methods, the process design is reasonable and the technical concept ingenious, representing a bold and proactive innovation and breakthrough in the field of embroidery.

[0054] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: A method for embroidering goldfish tail fins with double-sided, multi-segmented hooks in different colors. Figure 1 This embodiment shows an embroidery pattern (line drawing) containing a goldfish tail fin graphic 1. The embroidery pattern shows that the goldfish tail fin graphic 1 is composed of a tail leaf 8, which is formed by alternating adjacent linear tail fin spines 9 and plate-like tail fin plates 10. In this embodiment, each linear tail fin spine 9 is embroidered with a multi-segmented hook embroidery technique using double-sided, different-colored stitches. Ultimately, all the embroidered linear tail fin spines 9 lines naturally combine with the embroidery base material 2 within the area of ​​the goldfish tail fin graphic 1 to form a double-sided, different-colored embroidered goldfish tail fin.

[0055] Figure 2 This diagram illustrates the preparation of the embroidery base material 2, which contains the goldfish tail fin graphic 1, on the embroidery frame 12. The diagram shows that the upper and lower ends of the embroidery base material 2 are wrapped and stretched taut around the frame of the embroidery frame 12, while the left and right ends are tensioned to the frames on both sides of the embroidery frame 12 via tension threads 13. This is standard preparatory work before embroidery.

[0056] Figure 3 This diagram illustrates an embroiderer 14 performing double-sided embroidery with different colors on both sides of the embroidery base 2 simultaneously. The diagram shows the embroiderer 14 sitting beside the embroidery frame 12, performing the double-sided embroidery operation.

[0057] The following describes a method for embroidering a goldfish tail fin with a multi-segmented hook pattern using a three-section hook: The embroidery pattern containing the goldfish tail fin graphic 1 is first made on the taut embroidery base material 2 (see...). Figure 2 In this embroidery pattern, the goldfish tail fin graphic 1 is a mirror image on both sides of the embroidery base material 2. The embroidery base material 2 can be made of transparent, semi-transparent, or opaque fabric without restriction, but in this embodiment, a semi-transparent embroidery base material 2 is used. Then, using an embroidery needle 3 and two embroidery threads of different colors, the goldfish tail fin graphic is embroidered with different colors on both sides using a multi-section hook embroidery technique.

[0058] Define one of the two different colored embroidery threads as the first embroidery thread 4 and the other as the second embroidery thread 5 (see...). Figure 3 ).

[0059] Define the front side of the embroidery base material 2 as side 6 (first side), and the back side as side 7 (see...). Figure 3 Since this invention is a double-sided, different-colored embroidery, the goldfish tail fin pattern 1 is a mirror image on both sides of the embroidery base 2. Therefore, the front and back sides are only relatively defined. It is also possible to define the first side 6 as the back side and the second side 7 as the front side. This will not affect the final embroidery effect.

[0060] The goldfish tail fin pattern 1 is composed of a tail lobe 8 (see...) Figure 1 The tail lobe 8 is composed of linear caudal fin spines 9 and plate-like caudal fin plates 10 connected alternately (see...). Figure 1 The double-sided, different-colored embroidery is performed on each linear caudal fin spine 9, and the double-sided, different-colored embroidery lines on each linear caudal fin spine 9 are performed according to the following steps: Step 1: Preparing to start the stitch (see...) Figure 4 ) Select a point on the linear caudal fin spine 9 as the starting point 11 (see...). Figure 4 One end of the first embroidery thread 4 and the second embroidery thread 5 are positioned or fixed at the starting point 11. The first embroidery thread 4 is located on one side of the first surface 6 of the embroidery base material 2, and the second embroidery thread 5 is located on one side of the second surface 7 of the embroidery base material 2. The second embroidery thread 5 is threaded onto the embroidery needle 3.

[0061] In step one of this embodiment, one end of the first embroidery thread 4 is positioned or fixed at the starting point 11. Specifically, the embroidery needle 3 is first threaded onto the first embroidery thread 4, and then a knot is tied at one end of the first embroidery thread 4. Next, the embroidery needle 3 is used at the starting point 11 to pass through the embroidery base material 2 from the second side 7 to the first side 6 and the first embroidery thread 4 is pulled until the knot is located on one side of the second side 7 and the first embroidery thread 4 is located on one side of the first side 6 (see...). Figure 4 ).

[0062] In step one of this embodiment, one end of the second embroidery thread 5 is positioned or fixed at the starting point 11. Specifically, the embroidery needle 3 is first threaded onto the second embroidery thread 5, and then a knot is tied at one end of the second embroidery thread 5. Next, the embroidery needle 3 is used to pass from the first side 6 through the embroidery base material 2 to the second side 7 at the starting point 11, and the second embroidery thread 5 is pulled until the knot is located on one side of the first side 6 and the second embroidery thread 5 is located on one side of the second side 7 (see...). Figure 4 ).

[0063] The method used in this invention to position or fix one end of the first embroidery thread 4 and the second embroidery thread 5 is not limited to the knotting method described above. Knotting is not required; the thread can be fixed or positioned solely by the friction between it and the embroidery base material 2. Other methods can also be used, such as using transparent adhesive for positioning or fixing.

[0064] In step one of this embodiment, the starting point 11 is selected at one end of a linear caudal fin spine 9 near the goldfish's caudal peduncle. However, the present invention is not limited to this, and other points can be selected, as those skilled in the art will understand.

[0065] Step Two: First Layer of Forward Multi-Section Hook Embroidery (This embodiment uses a three-section hook, see...) Figure 5 and Figure 6 ) The first step is to embroider the first layer of the embroidery, using a combination of long and short stitches on the first section. On the first side 6, the first embroidery thread 4 is laid from the starting point 11 along the path of the linear tail fin thorn 9 towards the back of the fish tail.

[0066] Then, on the second side 7, starting from the starting point 11, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the back of the fish tail at intervals to form the first needle eye Y11 of the first layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the first long stitch C11 of the first layer on the second side 7.

[0067] Next, on the first surface 6, the second needle eye Y12 of the first layer is located near the first needle eye Y11 of the first layer and is hooked across the first embroidery thread 4. The embroidery needle 3 is passed from the first surface 6 through the embroidery base material 2 to the second surface 7 and the second embroidery thread 5 is pulled until the second embroidery thread 5 forms the first short stitch D11 of the first layer on the first surface 6. The first short stitch D11, because it hooks across the first embroidery thread 4, sews the first embroidery thread 4 on the first surface 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the first long stitch C11 of the first layer. At the same time, the first short stitch D11 of the first layer is hidden in the embroidery of the first surface 6 because of its short and small stitch length.

[0068] The second step involves embroidering the first layer of stitches, with a combination of long and short stitches on the second section, facing forward. Next, on the second side 7, starting from the second eye Y12 of the first layer, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the tail of the fish, with a certain distance between each eye as the third eye Y13 of the first layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the second long stitch C12 of the first layer on the second side 7.

[0069] Next, on the first surface 6, the fourth needle eye Y14 of the first layer is located near the third needle eye Y13 of the first layer and is hooked across the first embroidery thread 4. The embroidery needle 3 is passed from the first surface 6 through the embroidery base material 2 to the second surface 7 and the second embroidery thread 5 is pulled until the second embroidery thread 5 forms the second short stitch D12 of the first layer on the first surface 6. The second short stitch D12, because it hooks across the first embroidery thread 4, sews the first embroidery thread 4 on the first surface 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the second long stitch C12 of the first layer on the second surface 7. At the same time, the second short stitch D12 of the first layer is hidden in the embroidery of the first surface 6 because of its short and small stitch length.

[0070] The third step is to embroider the first layer of stitches, with the third section featuring a combination of long and short stitches. Next, on the second side 7, starting from the fourth eye Y14 of the first layer, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the tail of the fish, with a certain distance between each eye, to form the fifth eye Y15 of the first layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the third long stitch C13 of the first layer on the second side 7.

[0071] Next, on the first side 6, the position near the fifth eye Y15 of the first layer is used as the sixth eye Y16 of the first layer. The needle 3 is then passed from the first side 6 through the embroidery base 2 to the second side 7 and pulled by the second embroidery thread 5 until the second embroidery thread 5 forms the third short stitch D13 of the first layer on the first side 6. The third short stitch D13, because it is connected to the first embroidery thread 4, sews the first embroidery thread 4 on the first side 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the third long stitch C13 of the first layer on the second side 7. At the same time, the third short stitch D13 of the first layer is hidden in the embroidery of the first side 6 because of its short and small stitch length.

[0072] Continue this process until the desired embroidery length is reached. The desired embroidery length refers to the length of the embroidery to be achieved. For machine embroidery, the length is pre-set; for hand embroidery, there is some degree of arbitrariness.

[0073] This embodiment uses a three-section hook to represent the embroidery method of the present invention, but the present invention is not limited to this; two, four, or even more sections can be used for hooking. The specific method can be determined according to actual needs. The actual needs mentioned here mainly refer to the length and thickness of the embroidered linear tail fin spines 9, as well as the variations in thickness and color that occur with the length.

[0074] Step 3: The second layer is a reverse overlay of multi-section hook embroidery (this embodiment uses a three-section hook, see...). Figure 7 and Figure 8 ) Next, using the last needle hole from step two as the starting point for the second layer, and following the pattern of step two, reverse the process after completing the embroidery in step two: The first step is to embroider the second layer, reverse the first section of long and short stitches. On the first side 6, lay the first embroidery thread 4 from the last needle eye in step two along the path of the linear tail fin thorn 9 towards the front of the fish tail.

[0075] Then, on the second side 7, starting from the last needle eye in step two, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the front of the fish tail at intervals to form the first needle eye Y21 of the second layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the first long stitch C21 of the second layer on the second side 7.

[0076] Next, on the first surface 6, the second needle eye Y22 of the second layer is located near the first needle eye Y21 of the second layer. The needle 3 is then passed from the first surface 6 through the embroidery base 2 to the second surface 7 and pulled by the second embroidery thread 5 until the second embroidery thread 5 forms the first short stitch D21 of the second layer on the first surface 6. The first short stitch D21, because it is connected to the first embroidery thread 4, sews the first embroidery thread 4 on the first surface 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the first long stitch C21 of the second layer on the second surface 7. At the same time, the first short stitch D21 of the second layer is hidden in the embroidery of the first surface 6 because of its short and small stitch length.

[0077] The second step is to embroider the second layer of reversed, second section of long and short stitches. Next, on the second side 7, starting from the second eye Y22 of the second layer, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the front of the fish tail at intervals to form the third eye Y23 of the second layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the second long stitch C22 of the second layer on the second side 7.

[0078] Next, on the first surface 6, the fourth needle eye Y24 of the second layer is located near the third needle eye Y23 of the second layer. The needle 3 is then passed from the first surface 6 through the embroidery base 2 to the second surface 7 and pulled by the second embroidery thread 5 until the second embroidery thread 5 forms the second short stitch D22 of the second layer on the first surface 6. The second short stitch D22, because it is connected to the first embroidery thread 4, sews the first embroidery thread 4 on the first surface 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the second long stitch C22 of the second layer on the second surface 7. At the same time, the second short stitch D22 of the second layer is hidden in the embroidery of the first surface 6 because of its short and small stitch length.

[0079] The third step is to embroider the second layer of the reverse third section with a combination of long and short stitches. Next, on the second side 7, starting from the fourth eye Y24 of the second layer, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the front of the fish tail at intervals to form the fifth eye Y25 of the second layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the third long stitch C23 of the second layer on the second side 7.

[0080] Next, on the first surface 6, the sixth stitch Y26 of the second layer is located near the fifth stitch Y25 of the second layer and is hooked across the first embroidery thread 4. The embroidery needle 3 is passed from the first surface 6 through the embroidery base 2 to the second surface 7 and the second embroidery thread 5 is pulled until the second embroidery thread 5 forms the third short stitch D23 of the second layer on the first surface 6. The third short stitch D23 of the second layer, because it hooks across the first embroidery thread 4, sews the first embroidery thread 4 on the first surface 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the third long stitch C23 of the second layer on the second surface 7. At the same time, the third short stitch D23 of the second layer is hidden in the embroidery of the first surface 6 because of its short and small stitch length.

[0081] Continue this process until the predetermined embroidery length is reached. The length of the second layer of reverse multi-section stitches partially or completely covers the length of the first layer of forward multi-section stitches.

[0082] Step 4: Third layer of forward-facing multi-section hook embroidery (this embodiment uses a three-section hook, see...) Figure 9 and Figure 10 ) Next, using the last needle hole in step three as the starting point for the third layer, continue the embroidery process in the forward direction following the pattern established in step three: The first step is to embroider the third layer of the first section with a combination of long and short stitches. On the first side 6, lay the first embroidery thread 4 from the last needle eye in step three along the path of the linear tail fin thorn 9 toward the back of the fish tail.

[0083] Then, on the second side 7, starting from the last needle eye in step three, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the tail of the fish, with a certain distance between each eye as the first needle eye Y31 of the third layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the first long stitch C31 of the third layer on the second side 7.

[0084] Next, on the first surface 6, the second needle eye Y32 of the third layer is located near the first needle eye Y31 of the third layer and is hooked across the first embroidery thread 4. The embroidery needle 3 is passed from the first surface 6 through the embroidery base 2 to the second surface 7 and the second embroidery thread 5 is pulled until the second embroidery thread 5 forms the first short stitch D31 of the third layer on the first surface 6. The first short stitch D31 of the third layer, because it hooks across the first embroidery thread 4, sews the first embroidery thread 4 on the first surface 6 into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the first long stitch C31 of the third layer on the second surface 7. At the same time, the first short stitch D31 of the third layer is hidden in the embroidery of the first surface 6 because of its short and small stitch length.

[0085] The second step involves embroidering the third layer of the second section with a combination of long and short stitches. Next, on the second side 7, starting from the second eye Y32 of the third layer, the embroidery needle 3 is placed along the path of the linear tail fin thorn 9 towards the tail of the fish, with a certain distance between each eye Y33 of the third layer. It passes through the embroidery base material 2 from the second side 7 to the first side 6 and pulls the second embroidery thread 5 until the second embroidery thread 5 forms the second long stitch C32 of the third layer on the second side 7.

[0086] Next, on the first surface 6, the fourth needle eye Y34 of the third layer is located near the third needle eye Y33 of the third layer and is hooked across the first embroidery thread 4.

[0089] Continue this process until the predetermined embroidery length is reached, where the length of the third layer of forward multi-section stitches partially or completely covers the length of the second layer of reverse multi-section stitches.

[0090] This process is repeated until each line of the tail fin is embroidered according to the goldfish tail fin pattern 1. Finally, all the embroidered lines of the tail fin are naturally combined with the embroidery base material 2 in the area of ​​the goldfish tail fin pattern 1 to form a double-sided goldfish tail fin with different colors.

[0091] The following description addresses some variations of the present invention: 1. In the above embodiments, the first embroidery thread 4 or the second embroidery thread 5 in each layer are embroidered with the same thread diameter by default. However, the present invention is not limited to this. In fact, in the embroidery of a linear tail fin thorn 9 on the same side, different thread diameters can be used for embroidery and combination for the same line segment. This is a change that can be understood and recognized by those skilled in the art.

[0092] 2. In the above embodiments, in the embroidery of a linear caudal fin thorn 9 on the same side, different or the same thread colors can be used for embroidery and combination on the same line segment. This is a change that can be understood and recognized by those skilled in the art.

[0093] 3. In the above embodiments, in the embroidery of a linear caudal fin thorn 9 on the same side, different or the same thread diameters are used for embroidery and combination for different line segments. This is a variation that can be understood and recognized by those skilled in the art.

[0094] 4. In the above embodiments, in the embroidery of a linear tail fin thorn 9 on the same side, different or the same thread colors are used for embroidery and combination for different line segments. This is a change that can be understood and recognized by those skilled in the art.

[0095] 5. The embroidery method of this invention can be used not only to embroider the tail fin of goldfish, but also to embroider the dorsal fin, pelvic fin, and pectoral fin of goldfish, and even the fins of other fish. However, it is most typical for embroidering the tail fin of goldfish.

[0096] To demonstrate the practical effect of the embroidery method of the present invention, the following is provided: Figure 11 and Figure 12 . Figure 11 This is a front view of an actual goldfish embroidery piece. Figure 12 This is a reverse image of an actual goldfish embroidery piece. From Figure 11 and Figure 12 As you can see, the goldfish patterns (including the goldfish tail fins) embroidered on the front and back are mirror images of each other, and the colors are different, indicating double-sided embroidery with contrasting colors. The embroidery base material is a semi-transparent fabric. Figure 11 and Figure 12The goldfish tail fin in the image is embroidered using the double-sided, multi-segmented hook embroidery method of this invention. As can be seen from the embroidery, the lines of each linear tail fin spine are created using this method. Furthermore, the lines of each spine change in color, diameter, and number of overlapping layers along its length, starting from the tail peduncle. The basic pattern is: starting from the tail peduncle, the line color changes from dark to light; the line diameter changes from thick to thin; and the number of overlapping layers changes from many to few. Overall, the goldfish tail fin texture is clear, realistic, natural, soft, smooth, and dynamic. Compared to existing embroidery methods, this technique demonstrates a reasonable design and ingenious conception, representing a bold and proactive innovation and breakthrough in the field of embroidery.

[0097] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.

Step 4: Third layer: Front-facing multi-section hook embroidery Next, using the last needle hole in step three as the starting point for the third layer, continue the embroidery process in the forward direction following the pattern established in step three: The first step is to embroider the third layer of the first section with a combination of long and short stitches. On the first side (6), the first embroidery thread (4) is laid from the last needle eye in step three along the path of the linear tail fin thorn (9) toward the tail of the fish. Then, on the second side (7), starting from the last needle eye in step three, the embroidery needle (3) is placed along the path of the linear tail fin thorn (9) towards the tail of the fish, with a certain distance between each eye as the first needle eye (Y31) of the third layer. It passes through the embroidery base material (2) from the second side (7) to the first side (6) and pulls the second embroidery thread (5) until the second embroidery thread (5) forms the first long stitch (C31) of the third layer on the second side (7). Next, on the first surface (6), the second needle eye (Y32) of the third layer is located near the first needle eye (Y31) of the third layer. The needle (3) is then passed through the embroidery base (2) to the second surface (7) and pulled across the first embroidery thread (4) until the second embroidery thread (5) forms the first short stitch (D31) of the third layer on the first surface (6). The first short stitch (D31) of the third layer, because it crosses and hooks across the first embroidery thread (4), sews the first embroidery thread (4) on the first surface (6) into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the first long stitch (C31) of the third layer on the second surface (7). At the same time, the first short stitch (D31) of the third layer is hidden in the embroidery of the first surface (6) because of its short and small stitch length. The second step involves embroidering the third layer of the second section with a combination of long and short stitches. Next, on the second side (7), the embroidery needle (3) is placed from the second eye of the third layer (Y32) along the path of the linear tail fin thorn (9) to the back of the fish tail at intervals as the third eye of the third layer (Y33). It passes through the embroidery base material (2) from the second side (7) to the first side (6) and pulls the second embroidery thread (5) until the second embroidery thread (5) forms the second long stitch (C32) of the third layer on the second side (7). Next, on the first surface (6), the third eye (Y33) of the third layer is used as the fourth eye (Y34) of the third layer. The needle (3) is then passed through the embroidery base (2) from the first surface (6) to the second surface (7) and the second embroidery thread (5) is pulled across the hook of the first embroidery thread (4) until the second embroidery thread (5) forms the second short stitch (D32) of the third layer on the first surface (6). The second short stitch (D32) of the third layer, because it crosses the hook of the first embroidery thread (4), sews the first embroidery thread (4) on the first surface (6) into a long stitch of a different color. The long stitch of the different color corresponds to the second long stitch (C32) of the third layer on the second surface (7). At the same time, the second short stitch (D32) of the third layer is hidden in the embroidery of the first surface (6) because of its short and small stitch length. The third step is to embroider the third layer of the third section with a combination of long and short stitches. Next, on the second side (7), the embroidery needle (3) starts from the fourth eye (Y34) of the third layer and follows the path of the linear tail fin thorn (9) to the back of the fish tail at intervals as the fifth eye (Y35) of the third layer. It passes through the embroidery base material (2) from the second side (7) to the first side (6) and pulls the second embroidery thread (5) until the second embroidery thread (5) forms the third long stitch (C33) of the third layer on the second side (7). Next, on the first side (6), the position near the fifth eye (Y35) of the third layer is used as the sixth eye (Y36) of the third layer. The needle (3) is then passed through the embroidery base (2) from the first side (6) to the second side (7) and the second embroidery thread (5) is pulled until the second embroidery thread (5) forms the third short stitch (D33) of the third layer on the first side (6). The third short stitch (D33) of the third layer, because it is connected to the first embroidery thread (4) across the first embroidery thread (4), sews the first embroidery thread (4) on the first side (6) into a long stitch of a different color. The position and length of the long stitch of the different color correspond to the third long stitch (C33) of the third layer on the second side (7). At the same time, the third short stitch (D33) of the third layer is hidden in the embroidery of the first side (6) because of its short and small stitch length. Continue this process until the predetermined embroidery length is reached, wherein the length of the third layer of forward multi-section stitches partially or completely covers the length of the second layer of reverse multi-section stitches. This process is repeated until each line of the tail fin spines (9) is embroidered according to the goldfish tail fin pattern (1). Finally, all the embroidered lines of the tail fin spines (9) are naturally combined with the embroidery base material (2) in the area of ​​the goldfish tail fin pattern (1) to form a goldfish tail fin with double-sided different colors.
