I used silicon heart cupcake molds, with scalloped edges, which are available online and where cooking supplies are sold.
How to make it
Place broken, unwrapped crayon pieces into silcone heart molds.
If you want a specific color scheme, you can buy several different single-color crayon boxes, which are now available everywhere. Peel the crayons, and then break them into smaller pieces.
Set the crayon-filled molds on a baking sheet.
Place the tray and molds in your oven at 250 degrees until completely melted -- about 15 minutes.
Remove from the oven and allow to set before removing them -- about 30 minutes.
Then, just pop the crayons out of their molds -- and admire the swirls of color!
