Plain weave fabric is a type of fabric that is made by interlacing two sets of yarns or threads. The two sets of yarns are woven over and under each other in a simple alternating pattern. Two common types of plain weave fabric are etamine and BATISTE. Etamine is a lightweight, sheer fabric with a smooth finish. It is often used for curtains, blouses, and lingerie. BATISTE is a lightweight, semi-sheer fabric with a soft, silky feel. It is often used for shirts, dresses, and lingerie.
