ps dont precut your fabric. Its easier to put a square a bit larger than you want on the fabric, iron the fusible webbing on, let it cool then cut the design you want out. Fabric is firm easy to cut and you dont end up with stuff that gets stuck on your iron. I have done the dumb thing of cutting the fabric shape first then trying to put it on the fusible and iron it (DUH) and the stuff gets all over your iron. If your webbing is bigger than the fabric you will end up gooking up the iron and then going to the internet and looking up how to clean it off the iron. A blast!
