Picture those furniture ads with their matching sofas, love seats, and recliners, along with their twin end tables and two identical lamps. These types of design decisions are easy because there's little risk involved. You know it will look good because it looks good in the ad. But if the room becomes too predictable, it can become dull and lack personality.
Solution: Stay within your color palette, but don't be afraid to gently mix textures, patterns, and metals-chenille with leather, flowers with pinstripes, bronzes with pewters. Then add a couple of little surprises, such as an antique Chinese red table to complement the sofa or some Turkish pottery to hold a bouquet of wildflowers. Result: instant pizzazz.
