Step One to finger-painting: get out the box of paint and canvas. Also, lots of wet wipes (not seen in these pictures but most certainly there) for when paint gets to places it shouldn't go, including Daddy's sofa, carpet, ottoman etc..
Step Two: Put on your paint-shirt! Although on the box of Crayola finger paint tubes, is indicated that colours may be washed off clothes, we've more or less written off this ex-pajamas top already.
Step Three: Concentrate on creating a masterpiece!
Step Four: Oops... erm. We did a bit of face-painting too, it would seem!
