This is a very simple project you could do with kids (or for yourself). There's not much to it, really. Paint toilet paper tubes with acrylic paint and draw faces on with chalk. If you want to preserve the faces, use a spray fixative, but part of the beauty of this project is that the chalk can be wiped off with a damp cloth and you can draw new faces. If you are doing a project with small children, be sure to use non-toxic paints and chalks and skip the fixative.
