In the past, sails were made out of a material called 'sailcloth' or 'canvas' which was originally made from hemp/flax fibers (linen). After the discovery of cotton this too was used as the source of fiber. In modern times, sails are rarely made from natural fibers and most sails are now made from synthetic fibers including nylon, polyester, aramids and carbon fibers. These sails are stronger and will not let the wind though. (In the past sail canvas had to be sluiced down to make it impervious to the wind - this made the sails and rigging heavy).
