Paint chip art! Start in the top right corner and attach double-sided tape to each corner of each paint chip. Line the first one up and then use it as your guide to lining up the rest. When you add the second layer overlap the previous row so the names of each color are covered up. Think of a phrase and cut out your vinyl letters to see how you like it.
