That inspired me to make a pendant out of shrink plastic stuff. The plan was perfect. I have a bunch of pretty gel pens and sharpie markers. I created my design. Then, being lazy, I decided to use my heat gun instead of a toaster oven or regular oven. Heck, my back hurts. Why bother with the oven?
Crafty Lesson Learned:
Yes, a heat gun works on shrink plastic. Just a small piece. Like less than 6 inches long. Anything longer turns into something out of a sci-fi movie.
Back to the drawing board... Oh, and gel pens aren't exactly what I'd call permanent on shrink plastic.
