Convention Pins: Shrink plastic pins

Picture coming soon.


  • Shrink plastic
  • Scissors
  • Glue (I like E6000)
  • Sharpies or another type of permanent marker
  • Prismacolor pencils: red and yellow
  • Oven or toaster oven
  • Pin Backs
  • Sealer (optional)
  • A shrink plastic primer. I prefer the Shrinky Dink brand of shrink plastic for one reason only, laziness. Shrinky Dinks comes already sanded, or "ruff n ready" as it is labeled. Other brands of plastic work just as well and some people actually use recycleable lids from containers to shrink.

    Create a picture of what you want your pin to look like. Shrink plastic shrinks about 40 to 50% depending on the brand of plastic. Then on the unsanded side (this will be the front) outline your picture with the Sharpie. Let dry for a minute so it doesn't smudge, then turn the plastic over. Color in the images with the prismacolors. You are now coloring the back of the piece and when it shrinks the color will still be seen through the piece. With the Sharpie on the other side, it gives the piece a three dimensional effect.

    Shrink the plastic in an oven or toaster oven according to the directions on the packaging. I prefer a toaster oven, but that is just personal preference. You can also use a heat gun but I find I get pock marks where I hold the piece down so it doesn't fly all over the place.

    If you have a two piece pin glue the pieces together. If you would like to seal the back of the piece do so now. Sometimes the primacolors rub off a bit the first few times it is touched. Glue on the pin back.
