I use Steam-A-Seam Lite 2 for my appliqué and I can get it on Amazon for a reasonable price. I'm taking a class in a couple of weeks and the instructor suggested the MistyFuse because it adds less bulk if you have multiple layers of fabric so I bought some of that on Amazon too. It's unbelievably thin (spider web like) so I'll see how easy it is to work with and whether I prefer it.
