Melted Crayon Sea Shell Crafts for Kids

We’ve always been big fans of melted crayon rock art. Fanatic, even. So when I first saw Asia’s post about melted crayon sea shells on Fun at Home with Kids, I knew we’d have to try it.

We did, and I shared photos in my post about awesome ocean crafts for kids last summer.

This year we made them again, using shells we brought home from the beach.

Here’s what we did, plus a few twists and turns that made our version this year super fun.

  • Sea shells
  • Crayons (Any will work, but wax- and soy-based crayons work the best)
  • Oven
  • Baking sheet
  • Oven mitt or winter mitten to protect your hand (optional but younger kids might find it helpful) or a pair of tongs to help hold the shell in place
  • Hot glue gun (optional)
  • Beads (optional)

*The shells that work best for this craft are larger, to hold the heat better, and even a bit weathered. Save the gorgeous, shiny shells to display as is.

Sea Shells


1. Select your sea shells then wash and spread them out on a cookie sheet.

2. Heat the shells in a 350 degree Fahrenheit oven for 5 to 10 minutes.

3. Take one shell out of the oven at a time, per person, to work on and place on a protected work surface (we used sturdy paper plates over a placemat for the most part).

4. Draw on the hot sea shells with crayons, being careful not to touch the hot shell with your skin. We used tongs or chopsticks to hold the shells in place as we drew on them.

Note: As when making melted crayon rocks, we keep a small bowl of ice water nearby in case anyone accidentally touches a finger to a hot shell.

Last year, we did the melted crayon drawing on the outside of the shells.

This year, we started the same way, but then tried the melted crayon on the shell interior and LOVED how it looked. Like little jewel cases.

We made a lot of melted crayon shells this way.

5. Let the crayon shells cool and dry.

6. Add a bead (as a faux pearl) with a drop of hot glue as we did, if desired.
