Drill is stout durable cotton fabric with a strong bias (diagonal) in the weave.[1] It can be used unbleached, although it is more often bleached or dyed. Drill is a versatile fabric that has been used in a variety of applications.  Light weight drill is used in clothing items such as shirts, safari jackets, blouses, and sports clothing. The heavier weights were often used in the past in corsets, and are nowadays commonly used in work clothing and uniforms. The fabric soon became a popular material for military uniforms, and after the war as veterans returned, they also became popular as a fabric for a dress. Heavy cotton drill is widely used for making cooks' uniforms (chefs' wear) because it is thick enough to protect the person wearing the fabric from heat. Drill has also been used to make cushions and other interior purposes but also for tarpaulins, tents, awnings and canopies.
