Hi! I finished several months ago a queen size GFG. Took me over 8 years but I didn't work on it all the time. I used freezer paper (for quilters not on the roll)I had 2 acyrlic templates, one for rotary cutting the fabric, and one (1/4" less) for the freezer paper. I am now working on a small wall hanging and have ordered the precut papers. I find I can only reuse them about 4 times (others will say more) To me it's an OK method, but I like the freezer paper method better (no slip, etc) but I only have the acrylics in one size. But years ago they used newspaper, cereal boxes, whatever they had available and they turned out beautiful. Good luck!!! A great take with you project.
