Have people do this who already draw, or who think they can draw. Need to have at least 3 people. Find an abandoned spot somewhere — can be inside or outside. Everyone should be able to sit down on something. Position yourselves across from each other. Draw each other for a couple of minutes. Then half the people switch positions, everyone switches paper. Draw each other again for 3 minutes — you are doing two things: drawing over the top of someone else’s drawing, and drawing a different person on top of that drawing. Keep going for x minute intervals until your drawings are done.
Time: at least 15 minutes including setup.
Materials:
bigger paper (large sketch pad size)
other drawing materials
headlamps if you need them.
