Kids Craft: How to Make Hearts out of Recycled Crayons

craftskids crafts

Earth Day is a perfect time to create a craft with your children that shows them how they can recycle something old and broken into something new and wonderful. Here's a project that will use your old, broken crayons to create new, heart-shaped crayons that are fun to use. They also make great birthday party favors or Valentines!

How to Make Hearts out of Recycled Crayons


  • Old crayons
  • Heart muffin tins (or any shape you want for your crayons)


First, collect all the old, broken crayons in your house and remove the wrappers.

Next, put the bits and pieces of crayons into muffin tins. Any kind works, and your new crayons will be the shape of the tins. We used heart tins to make heart-shaped crayons.

Put the crayon-filled muffin tins into the oven, preheated to 200 degrees, for between five and ten minutes. When the crayons have melted and become liquified, they're ready to come out.

Cool the crayons for at least thirty minutes or until they have completely hardened, and then pop them out of the tins, and you're done!

Color with and enjoy your new, repurposed and recycled crayons. Or you can always give them as truly fabulous, one-of-a-kind Earth Day presents!

What fun earth friendly crafts are you doing with your kids?
