Saw this on pintrest and decided to try it out. It's super easy and fun! You're supposed to use cardboard, but i used pieces of wood. Just find a board or cardboard you want to use, draw any design you like on it, trace it with craft glue. Let it completely dry. Then glue heavy duty foil over the dried design and rub it so the design comes through. Let it dry then use a rag to apply any color shoe polish (i used brown), pour it on the foiled design and gently rub it across your design. Done! :-)
