I use the subscription cards that come in magazines for my templates. They are the perfect weight and thickness for the hexie pieces. They hold up under repeated uses and can be recycled when they are finally worn out. I'm sure I'm not the only one who has lots more of these little cards than I need! The usual 3-5 per magazine means I'll never run out.
I also let my kids use these when they were little for practicing their scissor skills. They are easier to cut than paper because they aren't so flimsy. Or they can be used for other template shapes as well. There are lots of possibilities. Do you have any other ways to use these subscription cards that I haven't thought of? You know, in case I ever actually finish this hexie quilt...hahahaha.
Enjoy every hexie!
