Zili (also known as Dzili or Dzhili) refers to a flat-weave technique common in the Caucasus, particularly in Azerbaijan, in which additional weft threads are passed over several warp threads in a characteristic diagonal offset to create geometric patterns. The result is a robust, reversible textile with a slightly ribbed, diagonal surface texture. Zilis were traditionally used as floor coverings, wall hangings and furnishings, and are now sought-after collector’s items, identifiable primarily by their clear, graphic patterns and characteristic weaving technique.
