Figure 7 and Figure 8 As shown.

[0075] The present invention discloses a method for cutting trousers from a single piece of rectangular fabric. This method involves creating a one-piece trouser garment by cutting a rectangular piece of fabric into a cutting area. Specifically, a cutting area is positioned in the middle of the fabric, and within this area, structures such as the crotch seam, waistband seam, and trouser seam are located. Then, the entire fabric is simply folded and sewn together, thus completing the trouser production process. This eliminates a significant amount of cutting and splicing, avoiding substantial waste associated with fabric cutting and improving material utilization. From a material conservation perspective, this method achieves environmental protection. Furthermore, the single-piece fabric processing is convenient, significantly improving processing efficiency and reducing manufacturing costs for manufacturers. It also meets the personalized DIY needs of users, resulting in a significant improvement in both economic efficiency and user experience.
