What's the one thing I should know about wallpaper these days?
"Metallics!" says Janet Lee, author of Living in a Nutshell: Posh and Portable Decorating Ideas for Small Spaces. "But not the loud, retro, shiny papers that used to adorn 1970s suburban powder rooms." Now gold and silver wallpapers add a subtle sheen to patterns and create extra light in small spaces. Her second choice? Black-and-white prints that keep rooms looking clean and uncluttered, while adding drama. "I love over-scaled black-and-white flowers, especially when paired with a Tiffany blue chair or end table."
