My Walls Are Empty

My walls seem so empty now in my living room since I have rearranged my furniture. I have been trying to think what to put on them and can't come up with many different ideas. A friend of mine had a really good suggestion for one spot. She said I should look at buying some candle sconces. I love that idea and would love to hear from some others on different ideas. I have paintings and such, but would like a little something different. Got any ideas?
