Nainsook
Nainsook is a soft, fine, lightweight form of muslin. Muslin encompasses a broad range of fabrics of varying weight and fineness, but is always a plain weave, cotton fabric. The English word 'nainsook', documented from 1790 onwards,
derives from the Hindi word, which literally means "eye's delight".
Nainsook was often used to make babies' clothing or lingerie at least until the 1920s. Nainsook cotton was also often used to make bias tape in the 1950s and 1960s.
