Heart Shaped Play Dough

My daughter helped me make these for her preschool group. This is my favorite recipe for play dough. We were able to make eight 1-inch thick hearts by doubling the recipe. We used a rolling pin to roll the dough out to a 1-inch thickness and then used a heart shaped cookie cutter to cut them out. We are going to use these for an activity during a preschool lesson but I think these would be fun to make to give out as Valentine's as well.

Here is the recipe:

2 cups flour
1/2 cup salt
1 Tbsp cream of tartar
1 3/4 cups boiling water
2 Tbsp vegetable oil
food coloring

Combine flour, salt, and cream of tartar; mix well. Stir in boiling water, oil and food coloring. Cool 10 minutes. Knead until smooth. Store in airtight container.
