I love the Freezer paper method of PP. But I did not run any of my FP through a copier. I made multiple patterns by tracing or transferring my pattern to one piece, then adhering several pieces of FP together. You just hit them with the tip of a hot iron and it sticks them together. I usually did 4 at a time with my marked one on top. Then I followed the drawn lines with my sewing machine with no thread in the needle. This not only transferred an accurate pattern to all pieces, it also perforated my fold line so it folded with no effort. I made the below quilt using this method and had no issues with all the bias edges. I found I could reuse a pattern piece about 5 times before it quit sticking. The method is also very thoroughly described in Judy Mathieson's book "Mariner's compass, Setting a new course" which is where I learned the technique from. Oh and I did not use an add a quarter ruler, I just used my regular ruler when trimming. Some of my units were so large that the little add a quarter ruler would have been no help at all when constructing this quilt.
