What happens when you wash Mylar designs on clothing?
So do you use a piece of mylar like applique???
Yes you do. Then tear it off gently when you have embroidered the design. I have just used this on two designs, and when I can get hold of some more mylar, I will be embroidering everything that stands still!
Barb, Mylar is a sort of iridescent paper or plastic that is integrated into an embroidery and it gives nice reflections (cute with butterfly design)
