I made two of these little outfits today, one for myself and one for my mother. Piece of cake! I don't know if you have a need for a heat mat, but if you do, this is cheaper, but supposedly just as effective, as a commercial heat mat. And you get to use your power tools to make it! lol Here is a picture of my finished product. Maybe somebody should put a patent on it?
