Take a bit of string and drop it on the floor until you like the shape it makes. Decide which way is up, and crop the composition so the string intersects with the edge of your drawing on 3 sides. Draw the spaces around the string (the negative space). Feel free to use an eraser if it helps. Take a picture of your drawing and post it to our Facebook page.
