Historically, muslin was woven from extremely fine cotton yarn produced from a special variety of cotton known as Phuti Karpas (Gossypium arboreum var. neglecta), which thrived in the humid riverine regions of Bengal. The remarkable fineness of the fibre allowed weavers to produce textiles of exceptional delicacy, sometimes so fine that an entire length of cloth could pass through a ring.

Over time, the traditional muslin industry declined during the colonial period due to disruptions in local weaving systems and the rise of mechanised textile production.

In recent decades, weaving communities in Phulia and Shantipur in Nadia district have played a significant role in reviving this historic textile tradition. Banglar Muslin is woven using extremely fine cotton yarns on traditional handlooms, requiring exceptional skill and patience from the artisans.

The weaving process involves several careful stages including fine yarn preparation, starching, warping and delicate handloom weaving, often carried out under humid conditions to prevent the delicate threads from breaking. Because of the very high yarn counts and the precision required in weaving, the resulting fabric remains lightweight, breathable and soft, qualities that historically made muslin one of the most prized textiles of the world. Today, Banglar Muslin stands as both a revival of a historic textile tradition and a testament to Bengal's enduring handloom heritage.
