To create: Insert a piece of cardboard or bristol paper inside the sweatshirt to prevent paint from bleeding through. Soak a kitchen sponge in water; ring out excess, then gently dampen the sweatshirt. Use a wet paint brush to dampen the watercolor paints, then mix onto a plate to achieve your desired colors. Paint the design onto your sweatshirt. Let dry completely before wearing.
