Right now I have a big, empty space above my couch in my living room. It’s been this way for a year now. For me, that’s a long time to go with open wall space. I have been contemplating doing a salon-style wall above my couch, but am unsure how it will look. While I do have high, sloping ceilings, I do not have a huge living room and I don’t want to overpower the room or close it in with too much artwork. Here is some inspiration…
I’ll keep you posted…
Scope for the Imagination 
I love that style.. go for it!
I think you should go for it also! You can put up special photographs and even make some of your own artwork. It’s a very frugal yet stylish way to decorate a large wall area.
I think the photos of special places is a great idea…especially travel photos. Italy, Japan, etc. I could unify them by using the same style frame, like thin gold or something.
I think you should go for it! Have you heard the trick about cutting up butcher paper? You just cut it the size of the frames you want to hang, arrange it and tape it to the wall. Then you can live with it for a day or so before you put any holes in the wall.
I was going to say almost the same thing Kasey said about pictures and then painting stuff yourself. you are so good at that!
