Muslin

Muslin (/ˈmʌslɨn/ or /ˈmjuːslɨn/) is a loosely-woven cotton fabric which originated in Bengal in South Asia, which was introduced to Europe from the Middle East in the 17th century. It became very popular at the end of the 18th century in France. Muslin is most typically an unbleached or white cloth, produced from carded cotton yarn. It is often used to make sewing patterns, such as for clothing, curtains, or upholstery. Because air moves easily through muslin, muslin clothing is suitable for hot, dry climates.
