Upcycle Old Crayons

Turning your old crayons into new, exciting crayons is easier than you might think. We are using this batch for preschool valentines this year, and my five year old artist couldn’t be more excited.


  • Crayons
  • Boiling water
  • Silicone moulds


  1. First, pour boiling water over your crayons. Let them marinate for a few minutes and their wrappers will practically come off by themselves.

2. Next, snap the crayons into smaller pieces and sort the crayons into pleasing color groups in the silicone moulds. If you need help creating color groups, check this out.

3. Next, pop them in a 250 degrees F preheated oven for 15-20 minutes, or until crayons are completely melted.

4. Let them cool for an hour or two, or until completely hard. And voila! You’ve got yourself a new batch of crayons!

I hope you enjoy this process as much as we did. My little artist can’t wait to glue them to the front of his handmade valentines and gift them to his friends next week.

We hot glued the crayons to an envelope and invited friends to finish the enclosed artwork with the heart crayons.
