I'm painting rocks and plants again - trying to capture in watercolours Creeping Jenny cascading down the wall.
Painting requires really seeing what your looking at. It's hard and it takes time and concentration. The interesting thing is that when you stop and get up and walk around, for a brief period of time everything appears to be more vivid. There's a sense that the activity of painting and seeing has worked in reverse. You see better because you've painted.
So too, fitting stones together better and better is about learning to see them. Don't just look at them. See them in position. Paint with them. At some point a kind of after image will emerge to help us see of what it is we are looking to build.
