How to Make Shrinky Dinks Out of Plastic Lids
- 1). Sand the plastic with sandpaper. The experts at Craftzine say this will help the marker or colored pencil stick to the plastic.
- 2). Draw a design on one side of the plastic with markers or colored pencils. The experts at Do Science say that permanent color markers work best.
- 3). Cut the design away from the rest of the plastic using the scissors. Use a utility knife to cut fine details.
- 4). Cover the baking sheet with aluminum foil. This will protect the baking sheet from any chemicals released by the plastic.
- 5). Bake the plastic in a oven heated to 350 degrees Fahrenheit. According to the website Do Science, the shrinking process can take between 30 seconds and 2 minutes. The plastic will curl and shrink, and is done when it is flattened again.
