Everyone has his or her own way of drawing and coloring, which you can clearly see when you compare two people’s renderings of the same thing. But what if everyone’s working on the same canvas?
Choose a landscape or nature sculpture and give the first artist 10 minutes before he or she hands it to his or her teammate. Keep going until everyone has had 2 turns.
As an alternative, one person draws the outlines, next another colors them with watercolor, a third adds ink lines on top and a 4th adds some collage.
