Drawing is such a tangible experience. There is a small drawing in the British Museum.  A sleeping Hendrickje Stoffels by Rembrandt Van Rijn. He slept with her. Dirty old codger. It was drawn in 1654. The marks are spare, controlled and precise.  I used to stare at copies of it, when I was a student. This is one of my own sketchbook drawings. It’s always reassuring to return to something so simple.
