Penguin Footprint Art for Christmas. Super easy craft for children using stretched canvas. I used acrylic paint for the blue background and penguin bodies, and paint markers for everything else. An easy way to do painted footprint crafts with children is to set up in the bathroom (contain the mess / tile floor!) and fill the tub with warm water. As soon as your child is done making prints, stand the child in the tub and clean him/her up.
