Something good to take up wall space and is relatively inexpensive is a room divider. We have a big alcove in our formal living room and we hung one up in there. To get a framed pic that large would have been hundreds of dollars. I got the room divider at The Alley for about $100.
Mirrors can be cheap, too. I bought one at Home Depot that was marked down because the frame was a little banged up. I sanded it a little, painted it, put on a contrasting color, sanded the edges again, and it turned out great.
