- 1/2 cup cornstarch
- 1 cup baking soda
- 3/4 cup water
Pour all ingredients into a medium saucepan on medium-low heat, stirring consistently. Stir until the mixture starts to thicken and eventually looks like mashed potatoes, like this:
Remove dough from saucepan and put it in a bowl and cover with a damp towel. Let cool approximately 30 minutes, until dough is at a comfortable temperature to touch. Knead the dough thoroughly to get out any air bubbles. Roll out dough 1/4″ thick.
Cut out your ornament shapes. Or, if you have cookie stamps, stamp with an image, then cut out shape. The dough can start to crack after a few times of rolling out the dough. To help this, wrap the ball of dough in a damp paper towel and microwave for 15 seconds. This restores moisture to the dough and helps it to become pliable again.
Bake at 175 degrees F for 45-60 minutes. Then flip over and bake an additional 45-60 minutes, or until all ornaments are hard. Let cool then spray with a clear protective coating (I used Krylon gloss finish). If you just used cookie cutters instead of cookie stamps, you can paint the ornaments whatever color you’d like. Or have kids paint their own designs onto the shapes.
