Most any paper will do but after using every type even the made for paper piecing paper, like Peckish, I only use lightweight translucent vellum. It it super easy to tear away fast and is flexible. Saves me frustration and the dread of removing the paper. That is more important to me then saving a few dollars. It goes through the printer just like copy paper.

I've been paper piecing for 15+years and have always used plain old cheap copy paper. I shorten my stitch length and the paper tears away no problem. I never spend money on specialty papers. Sometimes I use cheap (99 cents a yard) muslin from Joanne's for foundations so I don't have to deal with removing paper.

I've used it a lot. I just buy the cheapest paper they have because its thinner and run it thru my printer or copier. Short stitches and folding the paper helps if you have trouble.

I have heard that people have bought the old fashioned tablets at the Dollar Store. The paper is rough, more like a newsprint, then they cut it down to be the size of copy paper and run it through their printers. I bought the Carol Doak newspaper style from Hobby Lobby and that can get pricey. I do like it a lot.

I have PP'd with copy paper and I found it to be a little thick and sturdy for me. Plus I didn't think to backstitch when I started and ended a seam and had issues with my seams coming undone. I have read that some people dampen the seams and that helps the copy paper tear away easier. I have not tried that.

I use copy paper all the time. I try to get the cheapest so it is thinner than your better copy paper.

Yeah I tried the freezer paper first but decided I preferred the vellum. Freezer paper isn't opaque like vellum, and doesn't seem to stick as well as a dab of glue stick.

I use newsprint paper that I buy at the art and teachers supply store. Comes 500 to a pack and works real well.

I like the vellum type paper and buy it on a roll at an office supply store in the drafting department. It is less expensive that way. I also use it to draw designs to quilt with. It tears off so nicely and leaves very little 'whiskers'. I use masking tape made into a ring (sticky side out) to get them off.

Thanks everyone for your help. I have my fabric cut, and I'm ready to try it!

Yes, I've done it. Be sure to have your stitch length at a 1.4 or 1.5 and be careful when tearing the paper off.
