What is "yunjin"

Yunjin, also called cloud brocade, is a traditional Chinese silk brocade made in Jiangsu since the end of the Song dynasty, and based on weft-weaving techniques from both the Song and Tang dynasties. It is shuttle-woven, and often incorporates gold and silver threads with the coloured silks. During the Ming dynasty, the yunjin weavers developed a technique of swivel weaving that enabled them to weave colourful designs onto a base fabric in other weaves, such as satin. Nanjing Yunjin Museum is currently the only specialized museum in Yunjin.
