Whoo hoo, I KNEW I had just seen one. Not a bad price, either.
I'm stuck in a room testing samples of a material, and luckily get to bring my computer in with me, cause it's 9 minutes between each! I went back through old mail, the trash, had to find it. A much better price.
I found these they are very expensive
also you can create a mylar design by using an applique design and put a stippling on it. The stippling will hold the mylar in place.
