Some of my favorite artworks done by the kiddos are done on an absolute whim... like this one. It was actually a sick day in our home today. The ballerina was diagnosed with a bilateral ear infection and spent much of the day resting. While picking up her prescription, I also got her a new set of pens and a notebook to help cheer her up. The notebook filled up quickly, and soon her new pens were sliding down my arms. She got a real kick out of pretending to be a tattoo artist, and soon my older son had dibs on the other arm. I have to admit, I really love my new ink.
Go ahead, let your kids have some fun, too! Just make sure your pens are safe for skin, and I think it goes without saying, make sure it's washable!
