Reserve 3 tablespoons of frosting; cover and set aside. In a medium bowl combine remaining frosting, desired extract (if using), and 2 cups powdered sugar. Knead in enough of the remaining powdered sugar to make a moderately firm claylike mixture. Divide into portions and knead in desired color food coloring. Keep mixture covered when not using.
