Draw the outline of a hand, very lightly in pencil, and then began drawing lines freehand across the paper. When part of the hand is in the way of the straight line, have each artist "crawl over" their finger or hand with curves and arcs. The optical illusion becomes very obvious if the lines were close together and the curves fairly strong.
