I have used the muslin and like it alot, my friend uses a fusible but sometimes she gets bubbles in hers from too much heat. The snow ladies I'm doing at the moment, I am using warm and natural basted to it, I like that look. Maybe draw yourself a square or circle & do a sample with a few different backings to see which one you like best. When I hand stitch my labels I don't put any backing on, but then I'm not so worried about the carried thread showing through on a light background.
