I spent a satisfying morning adding the first layer of flesh colour into the skin of the two figures, then took out the green / brown ground with a Payne’s grey brushed on and pushed with a nasty old dried out house painting brush for some grassy texture.
The grisaille is now beneath a glaze of Burnt Sienna , then highlights of Titanium White. I lay the paint on fairly thickly with a brush, then scrape it away with the knife so that the texture and fragments of the earlier layers show through. I’ll use a rag to clean up unwanted bits, but I like to leave random textures alone when they serve the painting. It gives the illusion that the painting has appeared from a series of accidents.
