Nothing anchors a room like a rug and nothing adds quick character to a space the way a rug does. I am partial to vintage Persian (modern day Iran) multi colored area rugs. The saturated reds and blues feel significant but in a neutral, non-invasive way. I like them paired with either antique or modern decor. While a sisal rug is hard on your bare feet, I like way it acts as a elegant cover up of a mediocre floor or a base for other rugs to be placed atop. Animal prints are also another great neutral. If you are spending upwards of thousands of dollars on a rug, you are going to want the rug to play chameleon for long time.
