The chalk will still be soft, but carefully remove them from the silicone molds. Transfer them to a paper plate.

- Part of the fun of doing this is you can use different shaped molds! You don't have to stick to a simple chalk shape but could use molds shaped like flowers, dinosaurs, eggs, gems, and more.
- This recipe makes one color of chalk. If you want to make more than one color, you will need to use more than one cup and double or triple the recipe, repeating the steps with different colors.
- If you don't want to make a large batch but want more than one color, simply mix the water and plaster of paris mixture together in one cup and pour half into a second. Then use an 1/8 cup of paint in each.
