Mad Maggie Designs features this recipe for making your very own, custom sidewalk chalk! Um, brilliant!
"What You Need:
Toilet paper or paper towel tubes
3/4 cup warm water
Small bucket or disposable container
1 1/2 cups Plaster of Paris
2-3 tablespoons tempera paint
What You Do:
1. If you are using paper towel tubes, cut each tube in half. Cover one end of each tube with duct tape. Cut as many pieces of wax paper as you have tubes. Each piece should be as long as the tube and about 4 inches wide. Roll up each piece of wax paper and slip it into the tube.
2. Pour the water into the bucket. Sprinkle the Plaster of Paris over the water and stir the mixture thoroughly with a spoon. Mix in the Tempera Paint (If you would like pastel colors, you can mix brighter colors of Tempura powder with some white.)
3. Place each tube tape side down, on a level surface. Pour the wet plaster mixture into the tubes. Lightly tap the sides of each tube to release air bubbles, then set the plaster-filled tube aside to harden for a few days. Once they are dry, peel off the tubes and wax paper. Your chalk is ready for action!"
Thank you, Leslie!!! You rock!
