Mix the ingredients together.
Pour the mixture into a mold. We used our insect molds, the plastic container that Buddy came in, and the flower mold that we used to make chocolate flowers. The molds don't lay flat (I guess I should have realized that), so we spilled a lot of the mixture during this process :)
Let your chalk dry for at least 24 hours, pop it out of the mold, and have fun!!! O loved drawing on her gigantic outdoor chalkboard :)
