If you secretly think all suzanis look alike, visit Uzbek Craft and think again. Owner Juraeva Mayram has the most exquisite collection of modern and antique suzanis, for the retail customer, that I've seen online to date.
suzanis.com is a good resource if you want to learn more about the traditional process of making suzanis. This site, which highlights ikat textiles too, is mentioned in Jonathan Adler's My Prescription for Anti-Depressive Living.
Another nice site based in London, suzaniinterior.com just uploaded a new selection of gorgeous embroideries but it seems online shopping isn't available yet. Hopefully later this month. In the meantime, as I've posted before, yurdan.com has a large selection of suzanis for sale, and oldworldimports.net, based in the U.S., has a small but beautiful collection including the piece below.
