How can I paper a small room?
The worst wallpaper in this situation would be a dark-colored paper with a small print, says New York designer Fawn Galli. "It makes the room gloomy, even smaller and—in the most dramatic cases—claustrophobic." Instead, go with a large, fantastical print, such as one of botanicals or birds. The oversized design creates the optical illusion that the walls are bigger.
