Description

Technical Field

[0001] The present invention relates to a sheet for small articles, a small article using the sheet for small articles, a teaching material set for decorating small articles including the sheet for small articles, and a method for creating a decoration of the small article.

Background Art

[0002] In leather products made of natural leather such as bags, scraps are generated in the manufacturing process, and conventionally, the scraps have been discarded as waste materials. The inventor of the present invention considered using the scraps of the leather products for small articles such as brooches and coasters, taking advantage of the texture of natural leather.

[0003] However, the inventor of the present invention thought that even if the natural leather familiar in leather products such as bags was simply used as a material for accessories such as brooches with high interest or coasters, it would be difficult to feel novel. And the inventor of the present invention has continuously conducted earnest research on whether it is possible to provide a small article having a high decorative value even when using the end materials of leather products.

[0004] On the other hand, there has been proposed an accessory such as a key holder that uses cowhide as a base material and uses the fabric of an old kimono as a decorative material (Patent Document 1). Specifically, Patent Document 1 discloses an accessory body 10 in which a decorative material 30 is overlaid on a base material 20 and joined with an adhesive. A flexible leather is selectively used for the base material of the accessory body, and a patterned fabric is selectively used for the decorative material 30. In addition, an accessory is shown in which a connecting portion of a hanging tool used to hang the accessory body 10 is provided on the accessory body 10 (Claim 1, Summary, and FIGS. 1 to 4), and it is described that cowhide is used as the base material 20 (Paragraphs 0017 and 0020).

[0005] The invention disclosed in Patent Document 1 mainly focuses on reusing cut pieces cut from old kimonos or obis of Japanese clothing as accessories, and in order to prevent wrinkles, cowhide is attached to the decorative material 30 with an adhesive as the base material.

Problems to be Solved by the Invention

[0007] As described above, in the ornament of Patent Document 1, cowhide is used as the base fabric and is not exposed, and the texture of the cowhide is not utilized. Also, as described above, since the purpose is to show the patterned fabric of used clothes such as kimonos as the decorative fabric 30, although there is a device for holding the decorative grains 41 such as beads and stones on the decorative fabric 30 (paragraph 0026 and FIG. 2), it does not give a new pattern to the surface of the ornament. That is, in the ornament of Patent Document 1, there is no room to create a novel decoration on the leather sheet.

[0008] Therefore, the present invention provides a sheet that uses natural leather, which is a waste material of leather products, and can apply a novel decoration while making use of the texture of the natural leather, aiming to solve the above-mentioned conventional problems.

Means for Solving the Problems

[0009] The present invention provides a sheet made of natural leather with a maximum width not exceeding 15 cm. The surface of the sheet is a decorative surface, and through-holes penetrating from the front surface to the back surface of the sheet are used as guide holes. A plurality of the guide holes are distributed or arranged on the front surface of the sheet, and by sequentially passing one or a plurality of threads through each of the guide holes, a sheet for small items capable of drawing a pattern on the sheet surface with the threads can be provided. In the present invention, the sheet has a maximum width of 3 cm to 10 cm, the sheet has a thickness of 0.5 mm to 10 mm, and in plan view, it has a contour of any one of a substantially circular shape, a substantially elliptical shape, and a substantially polygonal shape, or has a shape surrounded by curves and straight lines as its contour. Each of the guide holes has a diameter of 0.1 mm to 3 mm, and the distance between adjacent guide holes is 2 mm to 10 mm. The guide holes are distributed on the sheet surface or arranged on the sheet surface so as to be located at least on the contour of the pattern drawn on the sheet surface. By sequentially passing the thread through the guide holes using the guide holes as an index, it is possible to provide a sheet for small articles that can draw a pattern on the sheet with the thread and fix the thread presenting the pattern to the sheet. Furthermore, in the present invention, each of the guide holes is radially distributed around a point on the sheet. By passing the thread through each guide hole, it is possible to provide a sheet for small articles that can draw a point-symmetric geometric pattern centered on the point as the pattern. Moreover, in the present invention, it is possible to provide a small article that is any one of an ornament such as a brooch, a bag decoration, a strap, a key holder, a coaster, or a wall decoration, which comprises the sheet for small articles through which the thread has been passed. The ornaments such as the above-mentioned brooch include, in addition to the brooch, pendants, necklaces, badges, coats of arms, earrings, ear ornaments, hairpins, hair ornaments, bracelets, and anklets. Furthermore, in the present invention, it is provided with at least the sheet for small articles and a draft sheet which is a piece of paper. On the draft sheet, an illustration of the decorative surface of the sheet for small articles before the thread is passed through, indicating the positions of the guide holes, is printed. Before passing the thread through the guide holes of the sheet for small articles, the user of the sheet for small articles can determine the pattern to be drawn on the sheet for small articles by writing a line connecting the guide holes on the illustration with a writing instrument with respect to the guide holes on the illustration, and can draw the desired pattern on the sheet for small articles by referring to the line written on the draft sheet when passing the thread through the guide holes of the sheet for small articles and passing the thread through the guide holes of the sheet for small articles. Thus, it is possible to provide an educational material set for small article decoration. In the present invention, for a natural leather sheet with a maximum width not exceeding 15 cm, a plurality of guide holes penetrating from the front surface to the back surface of the sheet are provided in advance with a space between the guide holes, and by sequentially passing one or a plurality of threads through each of the guide holes, a method for creating a decoration of a small item by drawing a pattern on the sheet surface with the thread can be provided.

Effect of the Invention

[0010] According to the present invention, by using the through holes provided in the small item sheet made of natural leather as guide holes and sequentially passing threads through each guide hole using the guide holes as an index, a desired pattern can be drawn and fixed on the small item sheet, and the surface of the natural leather sheet can be easily decorated. That is, in the present invention, while making use of the texture of natural leather, it is possible to create a small item with a novel decoration of providing a pattern on the flat surface of the natural leather sheet with thread. In addition, natural leather such as cowhide is tough and excellent in durability, so that the small item can be used and the decoration can be enjoyed over a long period of time.

[0011] In particular, the present invention enables the creation of a small item with the above novel decoration by using the leather scraps generated during the manufacture of products using leather products such as bags. For this reason, the present invention contributes to the realization of a sustainable society that has been called for in recent years by reducing the natural resources discarded as scraps.

[0012] In addition, the present invention not only provides the final product as a small item, but also enables the creation of a small item with a novel decoration at home, and can provide a new hobby field. In particular, by radially distributing each of the above guide holes around a point on the sheet, when a small item is completed by passing a plurality of threads of different colors through each guide hole, a geometric pattern that looks like looking into a kaleidoscope can be shown as a pattern.

[0013] Furthermore, the present invention can provide an optimal teaching material for the site of teaching leather crafts such as DIY classrooms. For example, the present invention enables the teaching of a unique decoration method for small items with high preference, aiming at planar decoration similar to drawing, which cannot be experienced in sewing for shaping by sewing the edges of a plurality of leather pieces for manufacturing leather products such as bags. That is, the present invention can contribute to the education of a novel decoration method for small items without boring the students. Also, from the perspective of education, it can be provided not only for the above-mentioned DIY classrooms but also as a teaching material for home economics classes and club activities in junior high schools and senior high schools, and can also contribute to the development of children's creativity.

Embodiments for Carrying out the Invention

[0015] Embodiments according to the present invention will be described below with reference to the drawings. (Summary of the Present Invention) The teaching material set for small item decoration according to the present invention includes a small item sheet (sheet 1 for small items) and a draft sheet 4 which is a piece of paper (Figs. 1(A) to (C). That is, this teaching material set for small item decoration is a package of the sheet 1 shown in Fig. 1(A) and the draft sheet 4 shown in Fig. 1(C).

[0016] The sheet 1 is made of natural leather, specifically cowhide. The maximum width in the plan view of the sheet 1 does not exceed 15 cm. The sheet 1 is of a size that is discarded in the manufacture of bags and the like (Fig. 1(A)). In this example, the sheet 1 is circular in the plan view, and the contour (outer edge 10) of the sheet 1 presents a circle. Therefore, in this example, the above maximum width is the diameter of the sheet 1, and the minimum width is the same as the maximum width. Also, the contour of the sheet 1 is not limited to a perfect circle, and it may be approximately circular.

[0017] A plurality of through holes penetrating from the front surface 1a of the sheet 1 to the back surface 1b of the sheet 1 are provided as guide holes 2 (Figs. 1(A) and (B)). In the plan view of the sheet 1, the plurality of guide holes 2 are distributed or arranged at intervals between each other between the center (center) of the sheet 1 surface and the periphery (outer edge 10) of the sheet 1 (Fig. 1(A)). By sequentially passing one or a plurality of threads 3 through each of the guide holes 2 in Fig. 1(A), a pattern can be drawn on the surface of the sheet 1 with the thread 2 (Figs. 2(B) and (C) and Figs. 1(D) and (E)). The above center of the sheet 1, which is the reference for arranging the plurality of guide holes 2, is the center of the circle presented by the sheet 1. However, the position of the center is preferably exactly the center of the circle, but it may be slightly deviated. In this example, a guide hole 2 is also provided at the above center (the through hole 2 arranged at the center of the sheet 1 is called the through hole 20 as needed).

[0018] The draft sheet 4 is a piece of paper on which an illustration of the decorative surface (surface 1a) of the sheet 1 before the thread 3 is passed through is printed, indicating the position of the guide hole 2 of the sheet 1 (Fig. 1(C)). Before passing the thread 3 through the guide hole 2 of the sheet 1 for small items, the user of the sheet 1 can determine the pattern to be drawn on the sheet 1 by drawing a line connecting the guide holes on the illustration to the guide hole 41 on the illustration 40 with a writing instrument p with respect to the guide hole 41 on the illustration 40 (Fig. 2(A)).

[0019] As described later, as the thread 3, a plurality of different embroidery threads can be used. When making the above entry on the draft sheet 4, depending on the color of the thread 2, a plurality of colored pencils or pens of different colors can be used as the writing instrument p. After the above entry, the user can draw a desired pattern on the decorative surface of the sheet 1 by referring to the line entered on the draft sheet and passing the thread 3 through the guide hole 2 of the sheet 1.

[0020] Examples of small items made using the sheet 1 include ornaments such as brooches, bag decorations, straps, key holders, coasters, and wall decorations. Examples of the above ornaments such as brooches include brooches, pendants, necklaces, badges, emblems, earrings, ear ornaments, hairpins, hair ornaments, bracelets, and anklets. Hereinafter, embodiments of the present invention will be specifically described.

[0021] (Details of Sheet 1) The sheet 1 may have dimensions corresponding to the small items created within the above range. More specifically, for the above small items, it is preferable that the maximum width (diameter) of the sheet 1 is 3 cm to 10 cm, and the thickness of the sheet 1 is 0.5 mm to 10 mm. More preferably, the maximum width of the sheet 1 is 3.5 cm to 10 cm, and the thickness of the sheet 1 is 0.5 mm to 5 mm. Further, it is most preferable that the thickness of the sheet 1 is 0.5 mm to 3 mm. However, depending on the small items to be created and the content of the decoration, it may deviate from the above dimensions. Each guide hole 2 has a diameter of 0.1 mm to 3 mm, and the interval between adjacent guide holes 2 is 2 mm to 10 mm, and is distributed on the surface 1a of the sheet 1 or is arranged on the surface 1a of the sheet 1 so as to be located on the contour of the pattern drawn on at least the surface 1a of the sheet 1. More preferably, the diameter of each guide hole 2 is 1 mm to 3 mm. However, depending on the small items or decorative content to be created and the thread 3 to be used, the dimensions of the guide holes 2 and the interval between adjacent guide holes 2 may deviate from the above numerical values.

[0022] In the production of the sheet 1, an automatic cutting machine (CAD / CAM cutting machine) well-known for cutting the sheet 1 of the above dimensions from cowhide can be employed. Of course, it is also possible to cut the sheet 1 by pressing using a conventional mold or cutter. However, it is preferable to use the above automatic cutting machine in that there is no need to create a mold and the cost of mold creation can be reduced. Specifically, when using the above conventional mold, it is necessary to weld a plurality of needles for punching the guide holes 2 into the sheet 1 to the mold, and the mold becomes expensive. Also, in the production of the sheet using the above conventional mold, after cutting the main-purpose sheet for the bag by the above press, it is necessary to cut the sheet for small items by pressing. On the other hand, the above automatic cutting machine can cut the sheet for the bag and the sheet for small items to be created at the same time, and can shorten the manufacturing process and time.

[0023] Next, an example of the guide hole 2 will be described. The plurality of guide holes 2 may be distributed on the surface 1a of the sheet 1 without regularity, but when drawing a geometric pattern by passing the thread 2, it is preferable to arrange them to have a certain regularity. For example, in the sheet 1 of FIG. 1(A), the plurality of guide holes 2 are arranged on reference lines (virtual lines serving as main reference lines) a1 to a8 that radially extend from the center of the sheet 1 toward the outer edge 10 of the sheet 1 in the radially outward direction of the sheet 1, and on reference lines (virtual lines serving as sub-reference lines) d1 to d8 that curve and extend from the radially inner side to the radially outer side of the sheet 1 in the region between adjacent main reference lines a1 to a8. The main reference lines a1 to a8 are eight virtual lines that extend in eight directions from the center (guide hole 20) of the sheet 1 toward the radially outer direction of the sheet. However, the number of the main reference lines may be three to seven, or nine or more. Also, in this example, the included angles θ (FIG. 3(A)) between adjacent main reference lines (eight in number) are substantially equal (45 degrees), but those with unequal included angles are not excluded.

[0024] The sub-reference lines are symmetric with respect to the adjacent sub-reference lines with the main reference line sandwiched between them as the central axis. Specifically, the sub-reference lines d8 and d1 sandwiching the main reference line a1 are substantially hyperbolic lines that are line-symmetric with the main reference line a1 as the symmetry line (central axis), the sub-reference lines d1 and d2 sandwiching the main reference line a2 are substantially spindle lines (inverse hyperbolic lines) that are line-symmetric with the main reference line a2 as the symmetry line, the sub-reference lines d2 and d3 sandwiching the main reference line a3 are substantially hyperbolic lines that are line-symmetric with the main reference line a3 as the symmetry line, the sub-reference lines d3 and d4 sandwiching the main reference line a4 are substantially spindle lines (inverse hyperbolic lines) that are line-symmetric with the main reference line a4 as the symmetry line, the sub-reference lines d4 and d5 sandwiching the main reference line a5 are substantially hyperbolic lines that are line-symmetric with the main reference line a5 as the symmetry line, the sub-reference lines d5 and d6 sandwiching the main reference line a6 are substantially spindle lines (inverse hyperbolic lines) that are line-symmetric with the main reference line a6 as the symmetry line, the sub-reference lines d6 and d7 sandwiching the main reference line a7 are substantially hyperbolic lines that are line-symmetric with the main reference line a7 as the symmetry line, and the sub-reference lines d7 and d8 sandwiching the main reference line a8 are substantially spindle lines (inverse hyperbolic lines) that are line-symmetric with the main reference line a8 as the symmetry line. Each of the above reference lines serves as a guide for arranging the guide holes as virtual lines, and even if some of the guide holes deviate slightly from the above reference lines, they are not excluded.

[0025] (Regarding the thread 3) For the thread 3 passed through the guide hole of the sheet 1, well-known embroidery threads can be used. For the embroidery thread, one with a suitable count (thickness) for the size of the guide hole 2 is adopted. For example, a size 12 thread which is thinner than a size 5 thread may be adopted. Also, examples of the embroidery thread include rayon thread, hemp thread, silk thread, wool thread, and fancy thread. Before passing the thread 3 through the guide hole 2, it is preferable to loosen the gathers. By using a plurality of threads with different colors as the thread 3, the decorativeness can be improved. The color of the thread 3 includes not only chromatic colors such as red, blue, yellow, green, and purple, but also achromatic colors such as gray, white, and black. Furthermore, for the thread 3, those having a golden or silver luster may be adopted to improve the decorativeness. The thread 3 is not limited to the above-mentioned embroidery thread, and for beading or thin threads, those for other uses than embroidery may be adopted.

[0026] (Creation of a pattern on the sheet 1) For the needle n passing the thread 3, well-known needles such as embroidery needles and sewing needles may be adopted (FIGS. 2(B) and (C)). Pierce the needle n through the guide hole 2, and pass the thread 2 between the through holes 2 according to the desired pattern to be created. By using the guide hole 2 and using the stitch techniques used in embroidery or sewing, the desired pattern can be drawn on the front surface 1a of the sheet 1. As a basic example, for example, if expressing a dashed line, as shown in FIG. 2(B), pass the thread 3 from the back surface 1b of the sheet 1 through the guide hole 2 to expose the thread 2 to the front surface 1a side of the sheet 1, and then pass the thread 2 through another guide hole 2 and arrange the thread 2 on the back surface 1b side of the sheet 1 again. By repeating the operation, a dashed (broken) line can be expressed on the front surface 1a of the sheet 1. On the other hand, when wanting to express a continuous line, as shown in FIG. 2(C), the thread 3 can be looped in a chain by passing the thread 3 passed through another guide hole 2 through the guide hole 2 where the thread 3 has been passed first. FIGS. 1(D) and (E) are examples of different patterns created using the same sheet 1 with the same arrangement of the guide holes 2. As the thread 3, a plurality of threads 3a to 3c of different colors are used in FIG. 1(D), and also in FIG. 1(E), a plurality of threads 3d to 3g of different colors are used.

[0027] (Pattern guidance and freedom) The pattern and the way of expressing the pattern are at the user's discretion, and it is possible to express the pattern using well-known stitch techniques used in embroidery, for example, stitches such as cross stitch, blanket stitch, and chain stitch, or it is also possible to implement it using other stitch techniques. Also, in the last process of passing the thread 3, the thread 3 can be gathered with a French knot stitch at the guide hole 20 in the center of the sheet 1. On the other hand, for beginners, it is preferable to guide them specialized in a specific pattern rather than the freedom of the pattern to be drawn. Therefore, for beginners, the draft sheet 10 may be printed in advance with the procedure of passing the thread 3 through the guide hole 2 and the illustration after passing the thread.

[0028] (Finishing as a small item) After embroidering the sheet 1, if necessary, another sheet or seal may be attached to the sheet 1 as a lining with an adhesive or double-sided tape. When the target small item is a coaster, there is no particular need to attach other members such as metal fittings. When a user of the teaching material set creates an ornament such as a brooch as a small item, fasteners such as pins and metal fittings such as chains and straps may be attached to the sheet 1 separately. For example, when the above small item is a brooch, a safety pin may be fixed to the back of the lining sheet with an adhesive or tape.

[0029] (Modification example) Here, first, an example of the reference (virtual line) for the arrangement of the guide holes 2 suitable for forming geometric patterns seen in a kaleidoscope is shown. As basic examples, a radial arrangement (FIG. 3(B)) in which a plurality of guide holes 2 are arranged radially along the reference line (FIG. 3(A)) touched upon in the examples of FIGS. 1 and 2, and an enclosing arrangement in which the guide holes 2 are arranged along a plurality of annular reference lines (surrounding lines / virtual lines) b1 to b3 (FIG. 3) that (multiply) surround the center of the sheet 1 can be shown. The sheet 1 shown in FIGS. 3(C) and 3(D) above can also be implemented as a modification example.

[0030] Also, it is possible to implement a combination of the arrangements of the guide holes 2 shown in FIGS. 3(A) to (D). For example, FIG. 3(E) shows an example in which the arrangement of the guide holes 2 shown in FIG. 3(C) and the arrangement of the guide holes 2 shown in FIG. 3(D) are combined. What is shown in FIG. 3(E) can be regarded as having the guide holes 2 positioned on the reference lines a1 to a8 in FIG. 3(A) and the reference lines b1 to b3 in FIG. 3(C). As another way of looking at it, it can be regarded as having the guide holes 2 arranged on the reference lines a1 to a8 in FIG. 3(A) and the reference lines b1, b3 in FIG. 3(C), and additionally having one separate guide hole 2 in each of the regions c1 to c8 partitioned by the outer edge 10 of the sheet 1 and the reference lines a1 to a8. FIG. 3(F) shows an example of a pattern applied using the sheet 1 shown in FIG. 3(E). Note that the examples shown in FIGS. 1 and 2 can be regarded as modification examples of the arrangements of the guide holes 2 shown in FIGS. 3(A) and (B). FIGS. 6(A) to (C) show still other examples of the circular sheet 1 respectively. FIGS. 8(A) to (I) illustrate brooches created using the sheet 1 shown in FIGS. 6(A) to (C). FIGS. 6(D) and (E) show still other examples of the circular sheet 1 respectively. Also, FIGS. 9(A) to (D) illustrate coasters created using the sheet 1 shown in FIGS. 6(D) and (E).

[0031] In the examples shown in FIGS. 1 to 3, the sheet 1 is circular in plan view, but it may be elliptical, semi-circular (described later), polygonal, or may have a contour surrounded by curves and straight lines. FIG. 4(A) shows the sheet 1 as a polygon, i.e., an octagon, and adopts the arrangement of the radial guide holes 2 shown in FIGS. 1(A) and 3(B). FIG. 4(B) is an example of a pattern formed by the thread 3 on the sheet 1 of FIG. 4(A).

[0032] FIG. 4(C) also adopts a sheet 1 having a polygon (octagon) contour, but the arrangement of the guide holes 2 is the surrounding type shown in FIG. 3(C) (FIG. 4(D)). However, what is shown in FIGS. 4(C) and (D) is different from the sheet 1 of FIG. 3(D) in that the outermost reference line b3 in the radial direction of the sheet 1 is not a circle-drawing one, but a concave polygon (hexadecagon) having a portion recessed inward in the radial direction like the badge of a sheriff appearing in a western movie (a kind of star shape). FIGS. 4(E) and (F) show examples of patterns created by the thread 3 using the sheet 1 shown in FIG. 4(C).

[0033] As the polygonal sheet 1, an octagonal sheet 1 in FIG. 4 (front view) is exemplified. However, in addition, the sheet 1 may be a triangle, a quadrilateral, a pentagon, a hexagon, a heptagon, or a polygon with nine or more sides. When the contour of the sheet 1 is a polygon, it may have slightly rounded corners, as long as it is generally recognized as a polygon. FIGS. 6(I) to (K) show examples of a quadrilateral sheet 1. Each of FIGS. 11(A) to (F) is an example of passing the thread 3 through the sheet 1 shown in FIGS. 6(I) to (K). In addition, the polygon serving as the contour of the sheet 1 includes concave polygons in addition to convex polygons such as the above octagon. For example, the above polygon serving as the contour of the sheet 1 includes a star shape. FIG. 7(A) shows an example of a star-shaped sheet 1. FIGS. 12(A) to (D) are examples of passing the thread 3 through the sheet 1 shown in FIG. 7(A). When the small item created using the sheet 1 is a necklace, a pendant, a strap, or a key holder, as shown in FIGS. 12(C) and (D), a separate leather piece may be used as the ring 13 on the sheet 1 and attached by sewing or an adhesive, and a cord-like body 14 such as a chain or a leather cord may be passed through the ring 13. For other modification examples, the ring 13 and the cord-like body 14 may be provided according to the small item to be created. The polygon serving as the contour of Sheet 1 includes not only a regular polygon that is point-symmetric with respect to the center, but also polygons that do not have such symmetry. Furthermore, regarding the contour of Sheet 1, those composed of curves other than a circle, or those combining a straight line and a curve are also included. For example, Sheet 1 in a shape imitating a gourd or an ancient tomb (a front-rear circular tomb or a front-rear double tomb) is also included.

[0034] The arrangement of the guide hole 2 shown in Fig. 4(C) may be implemented in the circular Sheet 1. Fig. 5(A) shows an arrangement of an enclosing type guide hole 2 in a circular Sheet 1, but with a further modification to the outermost reference line b3 (Fig. 5(B)). As shown in Fig. 5(B), the reference line b3 has convex portions b31, b32 sandwiching a concave portion, presenting a concave polygon. The pointed mountain-like convex portion b31 projects outward in the radial direction of Sheet 1, and the trapezoidal or inverted cup-shaped convex portion b32 with a flat tip projects outward in the radial direction of Sheet 1. In addition, the arrangement of the guide hole 2 in Fig. 5(A) may be implemented in a polygonal Sheet 1.

[0035] Fig. 5(E) shows yet another example regarding the arrangement of an enclosing type guide hole 2 in a polygonal (octagonal) Sheet 1. In this example, the innermost reference line b1 is a square, the next inner reference line b2 is a substantially square with the sides between vertices slightly bulging outward, the next inner reference line b3 is a square, the reference line b4 immediately outside the reference line b3 is an octagon presenting a substantially square but with rounded corners, and the outermost reference line b5 presents an octagon along the octagon of the outer edge 10. Also, Fig. 5(E) is provided with auxiliary reference lines b6 extending along the sides (four sides) of the reference line b4 at four locations in the circumferential direction of Sheet 1 between the reference line b4 and the reference line b5. As shown in Fig. 5(E), the guide hole 2 is arranged along the above-mentioned reference lines and auxiliary reference lines. Fig. 5(F) shows an example of applying a pattern to the Sheet 1 shown in Fig. 5(E) by passing a thread 3 through it. Regarding the reference lines in each of the above examples, they specify the arrangement of the through hole 2 and do not restrict the arrangement of the thread 2 passed through the through hole 2.

[0036] As described above, the contour line of the sheet 1 may be composed of a curve other than a circle or an ellipse, or may be a combination of a curve and a straight line, and the above contour line may be a curve or a line combining a curve and a straight line. Regarding the contour of the sheet 1, in any of the above cases, it is not limited to being point-symmetrical or line-symmetrical as described above, and it can also be implemented as having no symmetry or regularity. Regarding the arrangement of the guide holes 2, it can also be implemented as having no symmetry or regularity as described above. For example, the guide holes 2 may be arranged on a reference line extending in a spiral shape.

[0037] Also, regarding the shape of the sheet 1, the contour of a character such as an animal, a person, a character appearing in a comic, or a so-called yuru-kyara (cute character) is used as the contour of the sheet 1, and the guide holes 2 are arranged on a (virtual) line depicting the inner part of the eyes, nose, and mouth of an animal, a person, or the above character, or the stamens and pistils in the case of a flower. By passing the thread 3 through the guide holes 2, it may be possible to simulate an animal, a person, a character's face, or a flower with the thread 3 together with the contour line of the sheet 1. Furthermore, the sheet 1 may be provided with a contour imitating the outer shape of a skull (skull / dokuro) (Figs. 6(F) to (H)). By arranging the guide holes 2 on a (virtual) line depicting the eye sockets and olfactory fossae and passing the thread 3 through the sheet 1 having a contour imitating the outer shape of a skull, it may be possible to express the facial features of a skull (Figs. 10(A) to (H)). Regarding the contour imitating the outer shape of a skull, it is possible to express the contour of a skull by imitating the shape of a skull in an ancient tomb as described above, for example, by imitating the skull with an arc and the jawbone with a square or a triangle. The above skull is not limited to a human skull and also includes animal skulls.

[0038] Regarding the sheet 1, when expressing the above characters, flowers, etc., the contour line is also drawn on the sheet 1 as being expressed by the thread 3, and the guide holes 2 are arranged on the (virtual) line where the contour line is drawn. By the user passing the thread 3 through the guide holes 2, the contour line is expressed. The contour (outer edge 10) of the sheet 1 itself may not contribute to the expression of the above circles, polygons, characters, flowers, etc.

[0039] When the sheet 1 is not circular, the center of the sheet 1 may be considered as the centroid of the sheet 1. Furthermore, regarding the sheet 1, it can also be implemented as a donut-shaped (ring-shaped) one in which the central portion 11 of the surface is punched out into a circle with a larger diameter by the above guide holes 20 (Fig. 7(B)). Examples of earrings created using the donut-shaped sheet shown in Fig. 7(B) are shown in Figs. 13(A) to (D). In Figs. 13(A) to (D), 15 indicates the earring fittings, and 16 indicates other decorations provided on the fittings 15.

[0040] An example of the above-mentioned semi-circular sheet 1 is shown in Figs. 7(C) to (E). The semi-circular sheet 1 may be configured as a single sheet 1 as shown in Fig. 7(C), but an additional arc-shaped sheet may be overlaid on the semi-circular sheet 1 as the sub-sheet 12, and the sub-sheet 12 may be fixed to the sheet 1 with the thread 3 for drawing the pattern. The sheet 1 and the sub-sheet 12 can be made of materials with different colors or shades to further enhance the decorativeness. An example of a necklace created using the sheet 1 shown in Fig. 7(C) is shown in Fig. 14(A). Also, examples of necklaces created using the sheet 1 and the sub-sheet 12 shown in Figs. 7(D) and (E) are shown in Figs. 14(B) and (C) respectively. In Figs. 14(A) to (C), 17 indicates the string for hanging the sheet 1 around the neck.

[0041] When the target small item is a coaster, a waterproof spray may be applied as needed. In addition, in the above, a teaching material set was exemplified, but instead of this teaching material set, small items created using the sheet 1 may be manufactured and sold, that is, small items as finished products may be distributed.
