This Canvas String Art Graffiti project is fun for kids and adults alike. While this is a spray paint project, you can use alternative paints or dyes for younger children. Makes a fun summer art project when your kids get bored.
Buy a mirror. Put letter stickers on it. Paint over the whole thing. Peel off stickers. (use canvas instead of mirror. Paint canvas what color you want your letters to be first, then letter stickers, paint over, peel off)
