Knotted refers to the process of interlacing, looping, or twining one or two cords to create a useful or decorative knob. For interior textiles, knotting is used in rug making, specifically oriental rugs. Produced by hand on a specialized loom, knotted rugs involve the weaver inserting knots into the rug and tying each knot by hand to create a durable floorcovering.
