You can load up a room with graphic black-and-white patterns if you include softeners, like scrollwork pillows, a rich cocoa sofa, and hits of juicy jewel tones (purple, teal, even the emerald green of a plant). A crazy wallpaper works best on just one wall, rather than four, and should be behind the main seating area. You want to enjoy it on your way into the room but not stare at it all the time.Minaret wallpaper, about $195 a roll, Osborne & Little, 877-322-7420.
