They are the perfect favor to make especially if you have a lot of broken crayons. You can melt them in a mold!
Tip: The mold does not even have to be Halloween related. For example, my mold is a flamingo I bought on sale. Instead, I used Halloween themed colors (like black, purple, and oranges). But if you do have a Halloween mold, feel free to use any color!
Total Time: 30 minutes + 24 hours in the fridge to cool/harden
