The thing about writing is that spending endless hours in front of your manuscript can turn your brain into mush.
Fortunately, when I steal away somewhere to do some editing I always make sure to bring my sketch book with me. I find that alternating between activities, in this case writing and sketching, helps me stay engaged for longer, ultimately being more productive.
While I finished writing summaries of all of my chapters yesterday (a kind of outline for those of us who decided we didn't need an outline) I also did some urban sketching.
These girls didn't let on once that they knew I was sketching them. Even when I held the image up and photographed in their general direction.
This is part of the Aqueduc (water treatment) in Verdun.
