Preheat your oven to 325 degrees Fahrenheit.
Cut a 4" x 6" rectangle out of your shrink film.
Draw your notebook paper design with colored pencils and a ruler on the rough side of the frosted shrink film.
Use a marker to write your message or draw an image.
Use a hole puncher to add a hole or holes on the side.
Lay your shrink plastic flat on a parchment paper lined cookie sheet.
Bake at 325 degrees F for 1 to 3 minutes.
You will see the plastic curl and twist as it heats up.
Wait 30 seconds after the last shrink plastic is lying flat.
Remove the cookie sheet from the oven.
Let the plastic fully cool.
Once plastic is cool, you can add a protective clear coat.
Let dry.
Add jump rings, keychains or tassles to your DIY keychain.
