This past weekend at the children's museum during the Harvest Festival, they had some great projects on hand and one of them was a great no-cook playdough recipe - Harvest Spice Playdough.
1 cup flour
1/4 cup salt
1 tsp oil
1/3 cup water (they added orange food coloring)
1 tbsp pumpkin spice seasoning
Mix all ingredients together then knead until it becomes a dough; store in a plastic bag. Done!
