Here’s a great recipe to make your own inexpensive play dough.
Step 1. In a large pot, combine 3 cups flour, 1 1/2 cups salt and 6 teaspoons cream of tartar.
Step 2. Next stir in 3 cups of cool water into which you have mixed 3 tablespoons vegetable oil and food coloring of your choice.
Step 3. Then, while stirring constantly, heat over medium heat. Keep stirring until the mixture coagulates and begins to pull away from the sides of the pan, or for about five minutes.
Step 4. Turn onto a cutting board and allow to cool slightly.
Step 5. Once it’s cool enough to touch, knead it until it’s smooth and has the consistency of play dough. Store in an airtight container.
