I use it when I make Bow Tuck purses. When I first started using I had a lot of frustration because I was just ironing it on and "thinking" it should be fussed. Then I read the directions. You really have to hold the iron in one spot using a pressing cloth for up to 10-15 seconds. You need to place the fleece down with fussing side up and then put your fabric on that. You are actually pressing onto the fabric. It takes a little time to move the iron from one spot to the next, but it really does fuse nicely. Try it on a test scrap first.
