I did these ink sketchbook drawings during my "Drawing in Motion" class that I teach at Tisch.. fabric studies with a big fan, as well as draped from a figure and a board. It's a great class that concentrates on capturing the motion and weight of figures and objects, and drawing from memory. It's something every animator must get really good at. Anyone who draws in public can relate to the advantage of seeing something for a split second and being able to capture it's gesture and energy! enjoy.
