Sewing has an ancient history estimated to begin during the Paleolithic Era. Sewing was used to stitch together animal hides for clothing and for shelter. The Inuit, for example, used sinew from caribou for thread and needles made of bone; the indigenous peoples of the American Plains and Canadian Prairies used sophisticated sewing methods to assemble tipi shelters. Sewing was combined with the weaving of plant leaves in Africa to create baskets, such as those made by Zulu weavers, who used thin strips of palm leaf as "thread" to stitch wider strips of palm leaf that had been woven into a coil. The weaving of cloth from natural fibers originated in the Middle East around 4000 BC, and perhaps earlier during the Neolithic Age, and the sewing of cloth accompanied this development.
