Canvas is often referred to as what type of cloth?

Canvas is often referred to as "duck" cloth. The term "duck" originally referred to a type of heavy, durable fabric that was closely woven and used in various applications, including sails, tents, and tarpaulins. Duck is a specific type of canvas that is woven in a plain weave and is known for its strength and durability. In essence, while not all canvas is classified as duck, the terms are often used interchangeably in certain contexts to describe sturdy fabrics.

Waxed cloth typically refers to fabric that has been treated with a wax finish to make it water-resistant, while sailcloth generally indicates materials specifically designed for making sails, which may or may not be canvas or duck. Denim, on the other hand, is a twill weave fabric primarily used for jeans and has different characteristics compared to canvas.
