Canvas is a very heavy fabric used for the manufacturing of sails, tents, awnings, backpacks, and other applications that require strength. It is also commonly used as a painting surface, general covers, and in fashion bags and shoes.

It comes "from the ancient olona and this from Olonne, a French city on the Atlantic coast where this canvas was manufactured (...). Derived from loneta" (Diccionario etimológico de la lengua castellana, Joan Corominas).

Physical characteristics
Modern canvas is generally made of cotton, although historically it was made of hemp. It differs from other heavy cotton fabrics, such as denim, in that it is woven in a plain weave instead of twill. Canvas is available in two basic types: plain and duck. Duck threads are woven tighter. The term duck comes from the Dutch word for "cloth," doek. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a numerical system of classification with the numbers reversed from the weight (a number 10 canvas is lighter than number 4).
