Here is an easy no cook, no cream of tartar playdough (play-doh) recipe.
3 cups flour
1/3 cup salt
2 tablespoons vegetable oil
1 cup water
Mix flour, salt and oil in large bowl. Mix water and food coloring. Add water mixture 1/4 cup at a time to flour mixture. Sir until it starts to come together. Knead until combined and smooth. Add a little more flour if it's sticky.
Our Measure Up Cups, Pots and Spoons are great for stamping in playdough. You can even use them as the measuring utensils when making it because the #12 cup equals 1 cup, the #6 cup equals 1/2 cup, etc.
