I don't use paper for paper piecing. I use the June Tailor nonwoven sheets. They come 25 to a pack for around $8 (or less if you have a JoAnn's coupon). They can be run through either an ink jet or lazer printer, you can see through it, and the best thing is that you don't have to tear it out. It does make the blocks a little stiffer, but that's a personal preference.
