Madeline Weinrib in New York sells some wonderful, graphic area rugs in all sorts of bright and muted and more subdued colors.  These were some of my favorites, which come in many other colors.  We have used these in the past for nurseries but I can also see them in a living room or an office to add some color and interest to the room.  Some of the more subdued colorways could be nice to add a little pattern to a monotoned master bedroom.   Check out her website www.madelineweinrib.com for more inspiration!  Best part?  These fabulous floor coverings are gently priced.
