I really love the look of wallpaper. It can be SO expensive though!
If you have a small wall or room to paper (like a foyer or a powder room or maybe the wall in your master bedroom that your bed is against), check eBay for some incredibly good prices. Here are a few of my favorites available now on the bay:
Vintage trellis
Red and white
Big medallion
Great black and white with birds
Big graphic floral
Gray Art Nouveau
Fun green trellis
Blue flowers
