Are you going to put more pictures above the couch?
If not, why not do the same thing with a different tablecloth higher up above the couch? I love your idea though and it looks great!![]()
I was looking for one in contrast (black on white) for the wall above the windows next to the couch BUT then I came up with this idea.
Im going to take this picture, divide into thirds and frame each piece then hang above the window. I am going for about a 24" X 36" for each piece, that should cover that space.

I have gone back and forth about putting something higher above the couch but I dont know if I want to do that. I think it might be overwhelming.
