In our house we are never afraid to get messy, but sometimes I just don't feel like cleaning up after painting. I came up with this idea of taping poster paper to the shower walls (would work just as well in the bath tub, but shower stalls are so much easier!)
Then I filled a paper plate with paint and gave them to Monkey to paint away! At first he did well and painted both posters I taped up.
Then he got tired of that and started painting the walls....and then the finger/hand painting started!! He did one hand print for each square of tiles..
