economical foundation papers for paper piecing?
For those of you who paper piece, is there something you use for foundation paper that is economical? I'm new to pp'ing---got a package of Carol Doak's foundation papers for Christmas. I love the papers, and am loving pp'ing, but at nearly $10 for a package of 100 papers, that's 10 cents a sheet. Too expensive (for me) to be practical, if I want to keep paper piecing. I have tracing paper, but I doubt that would go through the printer, and I'd rather not hand trace every block in a quilt. I was thinking white 15 lb. continuous perforated computer paper might work, but don't have any to try. Have any of you used that for pp'ing, and how did it work? Or is there something else out there I haven't thought of? Thanks in advance for any help.
