Li suggested I make a sort of visual record- perhaps a 'stop-start' animation with a commentary of some kind, showing how I make a painting, and publish the video online (perhaps on Youtube?). I think this would be interesting, although the first thing I need to say is that I  am not sure how I do it either!  I remember something Francis Bacon said about setting up the circumstances in which a painting can happen, and my own working method is certainly along those lines. I do very little concrete planning, and rely on 'getting into the mood' and improvising as I go. So I would be unlikely to be able to provide a foolproof step by step explanation of method. But I will be thinking about how this video/animation thing might be usefully and interestingly done.
