This is an easy Pinterest project made with mostly free supplies. Go pick up some paint chips and paint sticks from the hardware store. You will need to acquire some clothespins. Then start gluing. I ended up using wood glue, when both hot glue and modgepodge failed me, resulting in warped paint chips. I cut the pieces to fit before gluing. I tried it the other way and ended up with frayed edges.
Next thing you know, you have a great color matching game.
