Directions Mix and pour paints into a muffin pan or paper cups. Spread paper onto a flat surface and tape it down to keep it stable. Using spoons, dribble and drip paint onto paper, experimenting with different colors. While still wet, place a layer of cling wrap over the paint covering the whole surface. Use hands to smooth cling wrap and create smoothie designs underneath. Carefully peel off the cling wrap and allow paper to dry completely before using as gift wrap.
