Scan a finished coloring page into your computer in full color.
Either resize the image to approximately 3 - 4 inches wide using a photo editing program, or save it as a JPEG and print to the correct size.
Cut around the outside of the design, leaving a small part on top to punch a hole.
Punch a hole in the top of the design. When it shrinks, the hole won’t be large enough for the chain to go through. Make it larger by punching partial holes around the original hole.
Line a baking sheet with parchment paper, and put the design on top of it. Put another piece of parchment paper on top of the design. Preheat the oven and bake according to the package instructions.
Use a spatula to make sure the shape stays flat until it cools a little.
Now, you can be done at this point with the design, but I decided to add a coat of Dimensional Magic to it. Seal the ink with a spray acrylic sealer first and let it dry.
Squeeze a coat of Dimensional Magic all over the top of the design, avoiding the hole. Let dry 12 hours or until completely clear.
Cut a piece of ball chain and thread it through the hole to finish off the keychain.
