Nainsook is a soft, fine, lightweight form of
muslin.[1][2] Muslin encompasses a broad range of
fabrics of varying weight and fineness, but is always a
plain weave,
cotton fabric. The word 'nainsook' is first documented in 1790, and derives from the Hindi word nainsukh, which literally means "eye's delight".[1]
Nainsook was often used to make
babies' clothing or lingerie at least until the 1920s.[3] Nainsook cotton was also often used to make bias tape in the 1950s and 1960s.
