Homespun cloth is also called old cloth in the countryside of Qingpu. Homespun cloth dyeing and weaving techniques are all-cotton hand-woven textile techniques popular in the suburbs of Shanghai and the neighboring Jiangsu and Zhejiang regions. From cotton planting to spinning and weaving, the production of homespun cloth goes through dozens of processes, among which ginning, cotton spinning, spinning (shaking) yarn, beating yarn, dyeing yarn, winding yarn, warping cloth, joining machine heads, weaving, finishing the machine, and stretching cloth are crucial. In the past, girls often took homespun cloth as dowry, commonly known as "bottom of the box". The amount of homespun cloth is not only an expression of wealth, but also a symbol of the bride's ingenuity. Homespun cloth uses hand-spun cotton yarn and various colored threads to weave colorful geometric figures through repeated, parallel, continuous, spaced, contrasted and other changes in patterns, which has a strong artistic charm.
