Hessian, burlap in the United States and Canada, or crocus in Jamaica and the wider Caribbean, is a woven fabric made of vegetable fibres, usually the skin of the jute plant or sisal leaves. It is generally used for duties of rough handling, such as making sacks employed to ship farm products and to act as covers for sandbags, and for wrapping tree-root balls. However, this dense woven fabric, historically coarse, more recently is being produced in a refined state, known simply as jute, as an eco-friendly material for bags, rugs, and other products.
