Every famous saree carries the name of its home
Most of India's best-known sarees are named after the town or region that weaves them: Banarasi from Varanasi, Kanjeevaram from Kanchipuram, Paithani from Paithan, Patola from Patan. Many of these handloom sarees are protected by a Geographical Indication (GI), and pure silk pieces can carry the Silk Mark.
For a retailer or reseller, knowing where a weave comes from, what makes it special and how to tell a handloom piece from a powerloom or printed version is what lets you describe it honestly and price it right. Surat, in turn, produces large volumes of affordable sarees in synthetic fabrics, many inspired by these traditional designs.
