Splicing fabrics is a common method. There are two methods for reference: patchwork method. As the name implies, the rule of thumb is to choose regular graphic stitching fabrics, such as the most commonly used rectangle. The width of a shirt can be widened by longitudinal splicing on the back or sleeve of the shirt. There is also the irregular splicing method: irregularity is often formed by splicing multiple figures, such as lightning shape, flowing water shape, etc., and the width is increased by longitudinal splicing. On the contrary, transverse splicing increases the length.
