So, after you have pre-folded all the lines all across the paper (I use the tip of the seam ripper to lightly mark the line so I get a nice clean fold), glue piece number one in place, fold back and add piece number two to the seam line, and do not fold the paper back. Leave it folded and sew right next to that fold. Fold back the paper for piece three, add the piece and sew next to the paper fold. No paper to tear away, and that paper can be re-used mulitple times. My friend made 20 blocks with the same piece of paper.
I have heard of this and seen a You Tube video of it being done. Such a great idea. I think my search term was "paperless paper piecing" Thanks for reminding me.
