I’m always waiting for paint to dry, that’s a downside to Oil painting, although also a good thing - It means I can put the painting to one side for a couple of weeks (or more), sort of forgetting about it. When I then retrieve it from the shelf, I see it afresh and can often tell immediately if it is viable for further work. Usually they are and so it is like starting again, but the basics are down.
I currently have several paintings in the studio at that stage, but this week I took one such part-worked painting with me to the Exmoor National Park Centre in Lynmouth, where I completed it.
