I set out to make freezer paper stenciled onsies for a baby shower gift and realized that some of my designs were too intricate for freezer paper (mostly the tires on the jeep). I had some leftover blue vinyl that I wouldn't be using for anything, so I decided to use it along with some transfer paper to apply the stencils to the onsies before painting.
The first batch of stencils were way too big (I guess I forgot how small newborns really are!) so I had to start over and I was already in a time crunch so my sweet husband helped me out by blowdrying them. He tried to be nice and help even more by adding a second coat and ended up getting a blotch on the black guitar onesie. I had to improvise by adding some more blotches all around it using a cut-out of an oval shape. I think it looks cool that way!
I used my one of my huge vinyl stencils from the first batch to make our son a Superman shirt. After seeing this and helping me with the onesies, my husband decided to use the other huge stencils to make our son a brown jeep shirt with black tires and our daughter a guitar shirt. He was really into it too, he wouldn't even wait for the paint to dry before taking the vinyl off because he was too excited to see the finished product lol!
Because of the cost, I wouldn't recommend regularly using vinyl for this project but if you really want a specific design that's too hard to do with freezer paper, this sure works great! And you don't have to break out the iron :)
