I put my Cricut to use for this one since it was a bunch of lettering. I used freezer paper on the cricut with the shiny side up so it would stick. Just remember when you do this, you need to mirror the lettering. That way when you iron it on to the material, it reads the right way. I also learned that freezer paper will stick on a neoprene. I had my doubts at first, but I just needed to heat the iron up more before it would stick. It worked out great. I do recommend cutting out multiple copies of freezer paper for the stencils. I only had two copies and they were getting gummed up with paint. Thankfully, they held out till the end and we were able to finish all twenty koozies. It turned out to be a cute project and I hope the bachelorette party likes them.
