Use the melted crayon technique to make colorful seashell art. This is the perfect craft to do after a trip to the beach.

We’ve always loved making melted crayon art on rocks. It’s so fun to watch the crayons melt and mix into cool designs!

This time, we tried it on seashells—and it worked just as well. We used some shells we brought home from the beach, and the colors looked amazing on them.

It’s a fun way to use broken or old crayons, and each shell turns out a little different.

Here’s how you can make your own melted crayon seashell art!

How to Make Seashell Art for Kids

MATERIALS

Seashells*
Crayons
Oven
Baking sheet
Oven mitt to protect your hand
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.

INSTRUCTIONS

Pick your shells
Select your seashells, then wash and spread them out on a cookie sheet.
Heat shells
Next, heat the shells in a 350 degree Fahrenheit oven for 5 to 10 minutes.
Decorate!
Take one shell out of the oven at a time, per person, to work on and place on a protected work surface.

Draw on the hot seashells 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.

You can do melted crayon drawing on the outside of the shells or on the inside! We LOVE how it looks on the inside – like little jewel cases!
Add pearls (optional)
Let the crayon shells cool and dry. Add a bead (as a faux pearl) with a drop of hot glue as we did, if desired.

Aren’t they pretty?

Use your new and colorful shells for decoration, pretend play, or give them as gifts. You can even turn them into ornaments or pendants with the addition of string.
