We've been using old phone book pages at my church quilting group. Stitch with a small stitch and they just peel right off. No effort whatsoever. I made a Christmas wall hanging for my first paper piecing project. The instructor had run our pattern off on copy paper. Lordy Lordy, I like to have never got that paper off. I can't tell you how many stitches had to be reinforced because removing the paper broke the threads. Definitely not worth going through that.
