It sounds like you have a lot of good advise. But if its easier to find freezer paper, trace your pattern onto the non waxy side of the freezer paper, cut it out carefully and iron it onto your fabric (waxy side down), cut your fabric. Sometimes this is cheaper and easier , especially if you are not needing to use the piece more than 20 times. Also I make make multiple copies to speed up the process and they don't slip!
