 Azeri-populated areas of Georgia, mainly the districts of Marneuli, Bolnisi, Gardabani and Sagarejo, are famous for the production of Azerbaijani rugs of the Gazakh school of carpet-weaving, which also encompasses western Azerbaijan and northern Armenia.The rugs of this school are all wool, coarsely knotted in the symmetrical knot with a long, lustrous pile, and use strong red, blue, and ivory in bold combinations with relatively simple but dramatic designs.The city of Tbilisi, or Tiflis, is known as one of the important centres for Azerbaijanis' cultural development.
