When you think of mixed patterns, most people visualize a disaster. But, as evidenced from this photo, it can sometimes work with interior decorating. The crown molding pictured features several types of patterns and colors. The key? The colors are muted and the patterns all have gold to tie them together. Having mixed patterns with a common element is a great way to try this trend. My suggestion? Buy a few throw pillows and add them to your bedroom or living room. It only takes a little pattern to make a big impact.
