How to make your own shrinky sheets art:
1. Draw or trace a pattern on the frosted side and then color it with colored pencils, felt-tip pens, acrylic paint, or markers; Do not use water-based markers, crayons, or oil paint, because they will melt or burn in high heat.
2. Cut it along the pattern line by scissors, trim the edges to get good shape.
3. Use a hole punch to punch a hole where you plan on attaching the keychain (must do before shrinking).
4. Use a heat gun to heat it or place it on a parchment paper or a cookie baking sheet. Preheat the oven to 165°C/329°F. Bake for 1-3 minutes.
