What to draw
On your own
Yourself, right now. You on a Monday morning. Today's mood.
Your pet as a person. A favorite character.
An old friend or a teacher you miss.
With a group
Have everyone draw the same person, like a friend on their birthday or a coworker who's leaving. Then send the finished wall to that person.
Pull names from a hat so everyone draws someone different. Or have the whole class draw themselves.
