Cool huh? All you need are some watercolor paints and Saran Wrap, and voila, you've got something that looks quite impressive.
Apply the paint liberally in pretty color blocks and then add wrinkled Saran Wrap while it's still wet. After it dries, peel off the Saran Wrap and you'll have a piece of modern art good enough to frame and hang in your child's room. Thanks Artful Parent!
