I use paper. I print the hexagons on scrap paper, then cut them myself. They can be used at least 4 or 5 times before I need to discard them. I am working on my 3rd hexagon quilt. 2 GFG and this one will be diamonds. There are sites that paper or plastic templates can be purchased, that would be a time saver, but I'm cheap! And I really don't mind cutting the papers out. I print perhaps 8 or 10 sheets at a time, and spend maybe one evening cutting them. Won't have to make more for quite a while! Also brings out the "little girl" in me. Like cutting paper dolls. I'm sure you will find what works for you, and I do hope you enjoy the process as much as I do.
