Ahh yes! Freezer paper! All of my templates use it! For my 6" blocks, I design on paper, or copy a design. Then take a 8" square of freezer paper, iron just the top 1/4" to a blank 8 X 11" piece of paper. I then put that sheet down in the "receiving" paper drawer. The drawing goes in its place and I copy it!! Wonderful! Cut the pattern any way you want to make sewing and piecing it very easy. You can easily write of draw on the Papery side too if you want! Just remember, the original pattern will be reversed when copied. For most of mind it doesn't matter.
Yippee! I now have a huge bunch of patterns on paper that can easily be copied again. None has yet and I've been using this method for years!!
