Face Painting Tips on using brushes and sponges. It is hard to make mistakes in face painting. It’s all about having fun! You will need a jar of water, clean sponge or brush and paper towels. For more complex designs try doing sketch first or make a stencil out of plastic or card. Try to paint thinly as the skin is a flexible surface, thick and heavy coatings may crack. Place an old towel or paper towels around the shoulders. Have your model relax their face - no squinting. HAVE FUN!
