We also did a little fingerpainting project to go along with handwashing. It was more of a sensory activity than an art project, though. I brought in some dishwashing soap from home (yes, handwashing soap would have been more appropriate, but the kids didn't notice) and got out primary paint colors.
UPDATE 11/21/2013: First of all, the hand washing chart is great! Not only do the kids remember to wash their hands every morning, but they learned how to read each other's names! Secondly, I won the contest I linked up to. (see below) Yay!!
