I use Wonder Under exclusively. Heat & Bond is not meant for needling, but was designed for crafting. It's too stiff and almost impossible to hand needle. Steam a seam is also too gummy. There could be other products that work ok, but when I can get Wonder Under for $2.95/yd, minus my employee discount, I see no reason to spend more! I have a couple of little secrets for using Wonder Under. First of all, let it cool COMPLETELY before trying to peel off the paper. I have been known to pop my appliques into the refrigerator for a few minutes to speed up the process. Secondly, use a pin to score the paper and peel from the center of the shape, rather than from the edges. This eliminates fraying of fabric. I've been appliqueing for 30 years now, and I'm "sticking" to it!
