I love freezer paper! It is really useful in many ways!
Here's how I used it as a stencil for some craft projects...
I've also seen a couple of people do the stencils, and have it ready for kids to paint at birthday parties! Check out Grace Violet's birthday party for her little girl.
It's also great for covering tables for art projects and cooking!
