We held a workshop for the art students at Lycee Jules Verne.
During 4 lessons of art class broken up over two weeks between two groups, we had a talk about the history and current state of graffiti and street art. In the following class, the kids got a chance to help create a wall for their school. They were able to speay and draw their designs on the mural and then we came in later and cleaned it up and finished the work.
The projects was broken up over a period of 4 days and took a toatal of 10 hours to complete.
