most of the trademarks are sewn in a circle alone or with a thread on the left and right sides, which is not very firm. This kind of trademark is easier to remove. Take a sharp scissors or thread remover, slowly break some stitches first, and then pull out the sewing thread bit by bit according to the thread trajectory, so that the sewing thread will fall off and the trademark will be removed. However, some trademarks are not sewn separately, but are sewn together with the collar or neckline edge strip. If you want to dismantle them, you need to sew them up again, or cut off the trademarks along the edges of the seams, and then pick out a small part of the trademarks left from the seams.
