With this quick and easy finger paint your child can finger paint for just pennies. It's perfect for using on paper or in the bathtub. The dish soap makes this finger paint wash out of anything my girls have painted with it. Keeps for at least a week in airtight containers. A fun painting option is to cover a tray or cookie sheet with waxed paper and have your child spoon paint over it in different colors. Cover with another sheet of waxed paper. Your child can press down on the colors and watch them blend and move.
