Not my best idea ever as Princess A sat on Princess G's paint and Princess G sat on her own painting. The paint soaked through the smocks and onto their clothes, but it did mostly wash off. Besides the paint all over the girls had a blast. They can't wait for another painting day outside. I think they might have to wait until late spring as the rainy, blustery fall weather in here in full force. I just love those smocks, they were mine once upon a time.
