Sisal, arrowroot, and jute: telling the natural fibers apart by weave and hand
The natural-texture family covers several distinct plants, and each has a coarseness, color, and character worth knowing before it goes on a wall.
Natural-fiber wallcoverings are often grouped as grasscloth, but the label covers several different plants, and the differences in fiber decide the look and the feel. Three of the most common are sisal, arrowroot, and jute.
Sisal comes from the leaves of Agave sisalana, a stiff, strong fiber that also makes rope and matting. As a wallcovering fiber it reads coarse and hard-wearing, with a pronounced, slightly wiry texture and a pale natural tone that takes dye well. Its strength is the point: it gives a bolder, more rugged weave than the finer fibers.
Arrowroot is the fine end of the family. It is a thin, delicate fiber, closely woven, producing a tight, even texture and a subtle, almost refined surface compared with the coarser grasses. Because the strands are slim and uniform, an arrowroot weave shows less of the dramatic thick-and-thin variation that marks a bold grasscloth, which makes it the quieter choice where the texture should whisper rather than shout.
Jute sits in between and is one of the most familiar bast fibers, taken from the stalk of plants in the Corchorus genus and long used for sacking and twine. In a wallcovering it brings a warm, slightly golden tone and a soft, matte texture, with more give and a gentler hand than stiff sisal.
Telling them apart by hand is a good habit before specifying. Sisal feels firm and wiry, arrowroot feels fine and smooth for a natural weave, and jute feels soft and warm. All share the traits of natural fiber: real color variation between batches, no printed repeat, and a delicacy that vinyl does not have. Choosing among them is really choosing how coarse and how loud the texture should be.
