Here is a stencil method I had completely forgotten about until I began doing a little research. Lo and behold, there is a wealth of information about Freezer Paper Stenciling on the web! Whether you stencil professionally or just want to give it a try at home, this is a very simple and inexpensive way to stencil. 
I readily admit, I have not used this method in a very long time, so I will defer to some of the other sites that show this art and give clear “how to” instructions:
“Unwind, Sit, Relax and Knit A Bit” gives a very clear step-by-step guide to stenciling with freezer paper stencils on “onesies“. Too cute! These would make a great gift.
The Craftser Blog has some very helpful tips about stenciling on fabric and using freezer paper for your stencils.
Over at Dabbled, you will find the cutest and very clever idea for stenciling on training pants, using freezer paper stencils! A great step-by-step tutorial is found here too.
Jean over at The Artful Parent shows off her freezer paper stenciled creations. She was inspired by reading Amanda’s post at Soule Mama, which features her adorable stenciled items.
Every post that I read had one common thread. They all were amazed at how easy this type of stenciling was. Take a look at their creative designs for inspiration and and some easy to follow instructions. I was quite inspired myself and think I just might have to incorporate this method somewhere in an upcoming job!
If you’re painting a wall instead of a tshirt or onesie, try Linda Buckingham’s Projection Stenciling method, which also uses freezer paper.
