DIY Crayon Hearts for Valentine's Day

Enjoy this tutorial to make Crayon Hearts — make them for Valentine’s Day or just for fun because you have too many broken crayons in the house.

Why not upcycle crayon pieces instead of throwing them out? Simply melt them into these cute hearts, or any other shape you can find molds for.

Crayon Hearts Tutorial

Crayon Hearts Supplies:

  • Heart-shaped aluminum or silicone mold (my silicone mold is from Ikea and the aluminum one from a thrift store)
  • 30+ crayons
  • Cutting board (or plastic placemat)
  • Large knife
  • Large bowl with water
  • Paper and glue gun with glue sticks, or glue dots if you want to make the Valentine’s cards

crayon hearts tutorialYou’ll need about 30 crayons to make 20 crayon hearts.

  1. Let the crayons soak in water for about 15 minutes.
  2. The most time-consuming part of this project is taking off the crayon wrappers. If you know of a technique that doesn’t mess up your nails, let me know.
  3. Heat the oven to 230 degrees and dry off the crayons, then cut them into little pieces on the cutting board.
  4. Fill the molds with the crayon pieces and put them into the oven.
  5. Once the pieces melt a little bit, after about 10 minutes, carefully add more crayon pieces to every heart to make them bigger.
  6. Once the crayons have completely melted, take out the mold(s) and let them cool down completely.

I used an aluminum mold for one batch and a silicon form for the other. I turned over the aluminum tray and banged it on the table, and the hearts  popped out. The hearts from the silicone form came out fine as well once I popped them out individually, but they are not as shiny as the ones from the aluminum mold. I actually prefer those hearts.

You could just use or gift the crayon hearts individually, or go a step further to glue them to these Valentine’s cards.

I used this free template to print out Valentine’s cards the heart fit on perfectly and glued it to the center with my glue gun. If it pops off, glue it down with Elmer glue or glue dots. Those will only work if your hearts are pretty flat on the back, which mine were not.

I scored all of the crayons with my serrated utility knife (or a sharp paring knife would probably work too). Then the labels come off in one beautiful motion. Try it out! I did your project based on the pictures from the Pin I saw. I had not seen your soaking instructions prior to me making them!

Thanks for the tip, Jessica!

I used hot water to soak mine and the wrapper came right off! It was awesome!

Wonderful, Chelsea!

I actually used a small paring knife to slice the wrapper off and it seemed to go faster than soggy paper. Love this project. My daughter is a Valentine’s baby so I always want a creative party favor! Thank you!

I love how easy and beautiful these are! I would make them but can you believe it? We don’t really have crayons anymore. My kids prefer markers.
