Sisal rope is made with the fibers found in the leaf of the Agave sisalana plant and has a very rustic look and natural feel. It is a hard natural fiber that is resistant to salt water and was initially used for rope on sailing vessels. Sisal can be easily damaged by moisture, ultraviolet (UV) light, and many common chemicals. Often found in the form of small twines and cords, sisal is an excellent option for medium-duty use on indoor plants, in the garden, for crafts, and for package bundling.
