Crofting, The process of bleaching linen by exposure to the air on grass. This method in Ireland and Scotland is yet in use for the full and soft bleaching of certain fine grades of linen fabrics. It necessitates the possession of very extensive grass parks in connection with works, and renders the process both tedious and subject to the influences of the weather. By far the larger part of linen is bleached by the use of chemicals, principally chlorine. [See Bleaching, Linen]
