See this latest pic on Ben Pentreath's blog: books don't HAVE to be orderly on a bookshelf, especially if there are other bold pieces/colors in the room. I live with my books and pull them out and sometimes haphazardly put them back on the shelf. I don't want to pull all of my bks to the edge of the shelf one by one! It seems fake to me.
The walls of Peter’s winter bedroom, which sits between the living room and the library, were stripped back and painted a soft green reminiscent of a typical 18th-century palette. (great images in the link)
