I didn't notice this till long after it was done. Sydney and Kenzie were here one day 'working' with my inks and stamps. After finishing their creations, they went upstairs to go home, using the wall in the stairway to help them on their way (I suspect the culprit is 2-year old Sydney). Since that wall needed painting anyway, I decided not to try to wash the handprints off and will just paint over them when the time comes. It's kind of cute, and very colorful.
