Natural fibers are grasses such as Sisal, Seagrass, Jute or Mountaingrass. These fibers can be blended with wool or linen. 100% wool pyle or wool/linen blends are also available. We offer standard sizes on this site; however, the materials come in 13'2" rolls and can be custom cut. Premium bindings, mitered corners and blind stitching also available. Please call The Fashion Floor Annex's special order desk at 203/930-7427 or e-mail us at email@example.com. The rugs are shipped directly from the factory.
