This is to clarify that it is inevitable. 2. Punching is generally used when flipping seams, and the hidden stitching has little impact on the stitching effect. However, if you have high requirements for stitching effect, please do not choose low-priced punching tools. You can choose cutting punching tools to reduce errors.
