Once the deep red enters, the whole room stops apologising. A flat, quiet wall suddenly has a top half and a bottom half, a warm side and a cool one, and somewhere for the eye to land. The two birds pull upward, so a narrow wall feels taller than it is. Hang it in a hallway, above a writing desk, or on a dining room wall where people sit long enough to look. It sits happily with dark stained wood, leather, brass handles and wool. Keep the wall around it plain busy wallpaper or a run of small photo frames will fight the linework and flatten the colour.
