DIY: Watercolor Air Dry Clay Ornaments

Did you know you can paint with watercolors on homemade air dry clay? You can find this project in my newest Christmas guide, Come to the Manger, but I wanted to share it here as well! This is a super frugal, fun project that holds up well over time. We painted these last year and they look as good as new on our tree this year.

What you need:

  • 1 cup baking soda
  • 1⁄4 cup cornstarch
  • 3⁄4 cup water
  • Twine for hanging
  • Rolling pin
  • Parchment paper
  • Star-shaped cookie cutters
  • Watercolor paints & paint brush


1. Stir the baking soda, cornstarch, and water in a small pot over medium heat for 5- 10 minutes until it clumps together but remains slightly wet.

2. Place the dough on a silicone mat or parchment paper to cool. Once cool enough to work with, roll out the clay with a rolling pin and let your child help cut with cookie cutters. To make into ornaments, poke a small hole at the top.

3. Bake ornaments on parchment paper at 175°F for 40 to 60 minutes or let air dry for 24-48 hours.

4. When the ornaments are completely dry, use watercolors to paint. Make sure the paint is not overly wet as this can make the dough soggy.

5. Let the painted ornaments dry overnight. Hang with twine and enjoy!
