I used Reynolds fun shapes muffin/cupcake liners in my muffin pan. Then I melted old bits of crayons from my kids pencil boxes at 250 degrees for 15 minutes. I then swirled gently with a toothpick ( it will look pinkish depending on what colors you add) and let cool. After they were cool, I popped them out and they are ready to go! They are awesome especially for preschoolers to work on their grip!
