I have started using the June Tailor foundation sheets for paper piecing. It is a little bit expensive, but it is non-woven and doesn't have to be removed!!!! And you can run the sheets through your printer / copier. I have found them at WalMart and at JoAnn's. It comes in packages of 25 sheets. Sorry, I can't remember how much I paid for the packages, but have started stocking up on it with my 40% coupons.
