Warp threads are those base threads that run the length of a carpet or rug. The warp threads interlock with the waft threads. The warp threads are commonly (although not exclusively) made of cotton on a woven rug and extends beyond the edge to form the fringe tassels. Weaving garments dates back thousands of years. Leviticus 13:47-59 (KJV) refers to mold infections in the "warp and woof" of garments. Carpet and rugs are large textiles foundationally crafted upon warp and waft threads.
