Rush is a paper material which resembles a rope or cord. It has a distinctive helical twist to it and can be unraveled. Rush was developed in the late 19th century as a substitute for rattan in wicker furniture, occasionally called paper fiber reed wicker. Sometimes a wire core is added to rush to increase its strength. A woven fabric of rush, called Lloyd loom paper fiber rush has been available since the early 20th century, largely used in the manufacture of wicker furniture. Alternatives to rush might include Oriental seagrass and Danish cord.
