I didn't draw or paint yesterday. I teach in the morning and we had a guest in the afternoon. Today was a little more drawing and some more of sky background. I paint on dry 640gsm Arches watercolour paper and have it on a vertical easel. When I do the 'wash' background, I allow the paint to 'well' at the bottom and mop it up with a dry brush. I try to get the washes as even as I can, but little variations can provide interest with a 'busy' painting. The paint does also tend to 'well' in the texture of the paper which is rough. I like the rough texture as, even though I try for photographic realism, when the painting is seen in reality, it looks like a painting! because the paper is dry when I work, the painted areas can expand because of the water but this flattens as it dries. Once finished, the painted area shrinks a little in contrast to the outer edge which has not had paint or water added, so I turn the painting over and 'wash' the entire back with demineralised water so that the whole sheet shrinks at the same rate and the painting remains flat.
