My children have always had a propensity to draw on everything but paper. Their canvas has usually been their own body.
Sometimes when there has been no more free space on their bodies, the dog or the house has had to do.
Now that they are slightly older, I expected that they would grown out of this phase, but alas, I guess they have not. They located a address stamper and proceeded to self address their bodies. It's like drawing, but only using a stamp and some blue permanent ink.
Now if only the postal service would only be willing to ship them somewhere...
