I just had another brainstorm..... at least that's what I am calling it!
When I was working on my Grandmother's Flower Garden quilt of hexagons, I made freezer paper templates. I stacked 4 to 6 layers of paper together, secured them with staples and cut out 4 to 6 hexagon templates at a time. I could use a dry iron to attach the plastic side to the wrong side of the fabric. When done, I could reuse the template several more times.
Just a thought...
