No needles or threads! Will not peel off after washing! Also convenient for hem-raising. The heat of the iron melts the adhesive tape and penetrates into the fibers, making it impregnated with the fiber, making it similar to sewing. Place the iron on tape between the cloth and the cloth you are sticking, place a wet press cloth on top and press with an iron for about 10 seconds to complete the adhesive. It can also be washed and dry cleaned. Also great for appliques and one-point embroidery.
