The trademark of clothes is too hard, which is usually a hard edge left after eager. If you look closely, you will find that there are traces like scalding on the edges. I am in the clothing business, and I know that some brands of clothes are also very particular about the mark, that is, the trademark design. They will use some lace to hold down the four edges of the mark, so as to improve the quality and prevent people from stabbing. In addition, you can try it.
