I am on my second GFG. I cut my templates from freezer paper and lay the dull side of the template to the wrong side of the fabric (which I have cut with the seam allowance). Then I iron the seam allowance to the shiny side of the freezer paper. It works GREAT! And you can use the freezer paper templates over and over.
Once you iron a few you get a rhythm going and it is really easy.
