This is a gesture drawing. They are fun to do, but complicated. You have to sit at the far edge of the bench with your arm straight, drawing by only moving your shoulder and/or elbow, holding the pencil at the back and so lightly that the teacher could just tap your hand and it would fly out. You have to scribble and draw in circles not using any straight lines and then when you get everything laid out you can go back and make a few areas darker. All while not picking up your china marker. (we use china markers not pencils for these) And it’s done in 1-3 minutes.
