Jamdani is a hand loom woven fabric made of cotton, which historically was referred to as muslin. The Jamdani weaving tradition is of Bengali origin. It is one of the most time and labor intensive forms of weaving hand loom weaving. In the first half of the nineteenth century, James Taylor described the figured or flowered jamdani; in the late nineteenth century, T. N. Mukharji referred to this fabric as jamdani muslin. Whether figured or flowered, jamdani is a woven fabric in cotton, and it is undoubtedly one of the varieties of the finest muslin.

It has been spoken of as the most artistic textile of the Bangladeshi weaver. Traditionally woven around Dhaka and created on the loom brocade, jamdani is fabulously rich in motifs.
