The six photos above show a sequence of steps as I painted the drapery on this foreground figure. I am working with the vitreous paint mixed with gum Arabic, the binder used in watercolors. Because the glass doesn’t absorb the water, one has to work fast to control the movement of the paint as the water evaporates. Working in a window means that the glass is vertical so one is constantly fighting against gravity while controlling the effects of dark and light. This is done with the blending brush, a large brush with long hairs from the badger. I will be explaining the significant tools of the process in another posting real soon.
