Afghan rugs (and more particularly, rugs woven by Afghan refugees in camps in Pakistan) come in a range of designs and qualities. Traditional rugs are dominantly red and very dark blue or black in coloration, although shades of brown and gold also exist. Better Afghan rugs have excellent wool and strong geometric designs from Turkomen and Belouchi sources. Vegetable-dyed rugs in traditional Ersari designs woven as part of the non-profit Cultural Survival project are often very nice, and in the last several years traditional Persian (Heriz, Bakshaish, and recently some fine Feraghan) and Caucasian (Kazak, Shirvan, etc.) designs done with handspun wool and vegetable dyes on wool and cotton warps have appeared. Some of these are exceptionally beautiful and are excellent values.
