If you are planning to do some weekend antiquing in Atlanta, don't forget Allan Arthur Oriental Rugs on Bennett St. Arthur is currently offering 20-40 % off all antique, vintage and contemporary rugs. And for a wide range of informative links and sources, visit his site Cyber Rug.
Shown top is a Turkish Oushak, circa 1930, followed by a contemporary Anatolian and a mid-20th-century Persian.
BTW: Arthur has a great selection of small rugs. Perfect for layering, or grounding an eclectic room as Ruthie Sommers did in this oft-posted bedroom from InStyle Home spring 2007.
Barrie Benson is also a fan of these patterned rugs, as seen in domino.
