Though mostly used for saris, Jamdani is also used for scarves and handkerchiefs. Jamdani is believed to be a fusion of the ancient cloth-making techniques of Bengal (possibly 2,000 years old) with the muslins produced by Bengali Muslims since the 14th century. Jamdani is the most expensive product of Dhaka looms since it requires the most lengthy and dedicated work.

Jamdani patterns are mostly of geometric, plant, and floral designs and are said to have originated thousands of years ago. Due to the exquisite painstaking methodology required, only aristocrats and royal families were able to afford such luxuries.
