Caucasian rugs are woven by tribal weavers of the region south of Russia, near the Caucasus Mountains, between the Black and Caspian Seas. This area includes the countries of Georgia, Armenia, and Azerbaijan. There are approximately 350 different tribes, speaking 150 different dialects in this area. Caucasian rugs, even though made by different weaving groups, still have very common characteristics. One common characteristic among Caucasian rugs is the positioning of similar shapes in different sizes next to one another. Another common characteristic is their colorful and bright palette. Colors of blue, red, purple, yellow, green, navy, black and beige can all be combined in one rug. The patterns are very geometric. The common designs tend to be stripes, crosses, squares, diamonds, hexagons, triangles, botehs, 'S' shapes (derived from old dragon designs), some very geometric animal figures such as crab and tarantula, and even sometimes geometric human figures.
