Hi Peggy:
The BEST paper I've used is the thin paper that we get in the mail from our stocks and bonds company...we don't read the BOOKS but I save them and use the paper. It's thin as onionskin and works so well for paperpiecing. Use extra small stitches and it tears right off when you are ready to remove the paper. Works great and it doesn't cost a thing. If you don't get these books in the mail you might just go to one of the financial folks in your town (stock broker) and ask if they have one you can have for quilting. They'll probably be really glad to get rid of them or at least save them for you.
