Weaving involves interlacing two sets of fibers called the warp and weft at right angles using a loom. Fibers used can include cotton, hemp, hair, roots, raffia, wool or fur. The warp runs lengthwise on the loom while the weft goes through the warp. Looms hold the warp in place and can be made of wood or other materials. Weaving has been used for over 5000 years to create clothing, rugs, baskets and tapestries. Early civilizations wove shelters and supplies for survival, while later cultures used weaving for artistic, social and religious purposes. Weaving methods and uses have evolved with history but remain an important craft today.
