.. there comes a point when something catches on the canvas, something grips on the canvas. I don't know what it is, you can put your paint on the surface? Most of the time it looks like paint, and who the hell wants paint on a surface? But there does come a time – you take it off, put it on, goes over here, moves over a foot, as you go closer you start moving in inches not feet, half-inches – there comes a point when the paint doesn't feel like paint. I don't know why. Some mysterious thing happens. I think you have all experienced it.... What counts is that the paint should really disappear, otherwise it's craft. That's what I mean by something grips in a canvas. The moment that happens you are then sucked into the whole thing. Like some kind of rhythm.
