Last night in David's class we were blessed with the lovely presence of Sara Streeter dressed in a beautiful flamenco (?) dress with a shawl. She is probably one of the most inspiring models I've ever had the privilege to draw. That one sketch in the bottom left was sooo gorgeous with so much movement, and all she was doing was sitting. Point being if you ever get a chance to draw her, take it, shes fantastic!
So the purpose of this pose was to learn how to handle fabric, both simplifying it and how to elaborate on the underlying forms.
(sorry for the horrible quality, these were on 18x24 and I had to take photos then try and fix the contrast in Photoshop)
