This is one of those wonderful projects that takes more than one artist. I put out the large spool and lazy susan with paper taped to each.
We started with markers and then decided to see how paint and paint brushes would work.
I showed the children how they needed someone to spin while they drew on the paper. They had to negotiate and cooperate. They took turns spinning and drawing without any adult intervention. This large rolling tube is just part of our school and I'm not sure where it came from. It is a PVC tube with a dowel and wood on the ends for easy spinning. The lazy susan was a wedding present but I think this is a much better use for it.
The end result was collaborative as well. What an accomplishment!
