We did five two minute poses, five five minute poses, two twenty minute poses and finally one that was half an hour. I did pencil sketches for the first ones and got out my conte for the longer poses. I only have a few colours which made it interesting. It is hard to believe that these are all the same woman but they are. She was twisted when she was laying down and that made the shapes very challenging. I only had a small 8.5" X 11" pad. I will bring a larger one next time.
