There was a man next to me in life drawing today who sounded as though he was having a wrestling match with his paper and charcoal. I could hear frantic bouts of scrubbing and heavy sighs, and when he'd finished he had made such a big pile of black charcoal bits under his easel, that he had to clean it up with a dustpan and brush. (Don't forget this is an art room and the odd bit of drawing materials usually get on the floor, but obviously not this much!)
It reminded me of a time when I made large charcoal drawings in the life room and ended up with black all over both sides of both hands and most of my face, along with various hand prints across my clothes. When I first started to draw in an A4 sketchbook it felt so small and difficult. These days, it's my preferred way of drawing, in a sketchbook with a nice pointy pencil. I still make smudges (believe it or not), it's just that I rub them out as I go along!
