It is widely thought that watercolor (“…the water rules”) is the most difficult painting technique, because it involves so much that is accidental. The picture is not a message, mirror, or narrative. The picture is an object. It is an object on which a number of peculiar things have occurred: it bears the tracers of the stumbling brush and paint. These are the accidents that the painter must control or, as the case may be, let them take control. You can never be entirely sure; spots and lines can cast off the reins at any moment – catch them if you can. Sometimes a miracle happens – a small miracle is no less a miracle, – and the painter just stands there, gaping and blinking: What happened? Who helped? Although I do miss the smell of turpentine sometimes, I have painted nothing but watercolors for the past seven years – large and small, from ten feet to four inches in size.
