Draw a simple sketch.

“A very simple sketch. I was wondering how to make anything of the pools where they store the live oysters when a tractor headed out do drop a load of tasty molluscs in the drink. I only had time to scribble in a horizon line and sketch the tractor before they left. Once they had gone I had to decide what to do with the rest. The paper needed to stand for the still pools so I lightened the whole sky with a thin white wash. Then I could apply full strength white for the rest of clouds.”

“This is Honfleur where we spent a couple of days on our way home. I was a little lost as to what to draw when this very large lady and her tall thin companion came down the street. I suddenly saw how they might be set against the shadowed facades. This was a very busy spot so I had to just scribble in whichever bits I could see between the crowds of tourists. Most of the work here is in the facades with lots of hatching.”
