Carpet making is a family tradition transferred orally and through practice, with carpet making and rug making being almost women's job. In the past every young girl had to learn the art of weaving carpets, and the carpets she wove became a part of her dowry. In the case of a newly married son, it was his mother who wove a large rug for his new household. Starting a new carpet meant a feast, but the completion of a rug meant an even greater celebration for the family. In the old days finished carpets were laid out in front of the house so that passers-by with the weight of their feet could make them even tighter than they had already been knotted. For the traditional process of carpet and rug making, men removed the wool from the sheep in the spring and autumn, while women collected dyestuffs and spin and dye yarn in the spring, summer and autumn. Azerbaijani carpets are divided into four large regional groups: Quba-Shirvan, Ganja-Kazakh, Karabakh, and Baku.
