I have a mid-century modern house, though I'm a traditional kind of girl. This is a very large -- 145" wide -- window that slides open from the right side and has a recessed space for the window treatment on the left side. (You can just see the existing vertical blinds folded into the recess on the left of the photo.) It is next to the master king bed and gets a lot of early morning light. I want a window treatment that will 1) allow opening the window at the right, 2) look up-dated and transitional, 3) works on a huge window. I am thinking possibly of shutters or a traditional drape that draws from the side, though I don't like the look of sill-length drapes very much. What ideas do you have?
