How to Recycle Crayons ~ Valentine’s Day Kids Craft

This project has it all – it is fun, inexpensive, quick, green and just plain cool. Since Valentine’s Day is just around the corner, I decided we would share our fun craft in the form of Valentines. Who wants to place bets on which kid has the coolest Valentine’s in preschool?!

Recycled Crayon Valentines

Restaurants dole out crayons by the handful. I try to refuse them when I can, but more often than not we wind up adding crayons to our collection. Since I can’t bare to throw anything away, we have more crayons than any kid can use. In addition to restaurant crayons galore, we have an ever growing collection of broken bits. The craft gives all of those extra crayons and broken bits new life.

What you need:

Remove the wrappers from your crayons and break into bits. Fill your mold with the bits. Place your mold on a cookie sheet (for support – trust me on this), and melt in the oven on 230 degrees for 12 – 15 minutes. (I put them in for 12 minutes, but they needed a bit more time so I watched until they were fully melted.)


  • If making crayons with little ones who won’t be able to help in the label removal process, remove the labels before inviting them to “help.” It is a process.
  • For my mini heart mold, I used approx 2 1/2 crayons per heart. (So for a 12-hole mold, plan on 30ish crayons)
  • Want bigger crayons? This mold makes 2 1/2 inch hearts.
  • After you make crayons in your mold, you won’t want to make food. Some of the cheap crayons will stain the mold.

How to Make Recycled Crayons
Once the crayons cool (several hours) pop them out and ta-da! You will be amazed how cool your new crayons look – I know I was! I’ve been wanting to do this with K for some time, and now that we finally got around to it I want to do it again with different shapes.

To make your own Valentines, download this printable. You will get six Valentine’s per 8 1/2 x 11 sheet of paper. I printed mine on white card stock and backed with red card stock that I edged with fancy scissors, but I added red border to the printable so you don’t have to.

Hint – use rubber cement to adhere your crayons to the paper so the crayons will come off easily and cleanly.

Happy Valentine’s Day!
