Grab a large piece of paper (bigger than a normal sheet of paper). Choose your medium. I'm planning on using acrylic paint for this project. Draw a line that divides your paper in half. Choose a subject. It helps if you choose something that has lots of angles and inside holes, otherwise your negative space side will look like a huge block. Plants work well. I'm going to do a palm leaf.
Day 1 (June 23): On one half of the paper, draw your subject in positive shape.
Day 2 (June 27): On the other half of the paper, draw your subject in negative shape (meaning draw everything around it).
