Before a line or a wash goes down on paper, I have a vision of what I am after. As the painting progresses I become doubtful that my first intentions are being fulfilled. Watercolour is the most demanding of all painting media: what goes down stays down, highlights have to be jealously safeguarded and washes have a mind of their own. In thirty minutes scores of things can go wrong and it is often the last brush stroke that does most of the damage. On completing a painting I am rarely satisfied.
It is not until later, after the shock of seeing from a different perspective, that I realize that what I originally perceived as a failure might have the makings of success. In the old days I would place the painting flat down on the floor and view it from all directions. Now, the image on the computer screen allows me the same detachment.
