Here's another great idea for vinyl...car window decals. These are just a couple that I had special requests for. The first one went on the back window of a Mustang, and says, "Momma's Pony". It also has the Mustang icon above the wording.
This second one is on the back window of an old El Camino. It says, "Get Trucked" and includes the Chevy "bowtie". I used SCAL2 and my Cricut to cut them both. I've also done a few smaller sized decals like this stick family. I put it on my sister's car back in December. It was so cold I couldn't feel my fingers, but it stayed put! Notice the pregnant mom...only 3 weeks until she'll need an updated version.
