The fabric itself is braided or woven onto a loom to create the structure of the rug. No base material or backing is used. The weft strands are simply passed through the warp strands.
A weaver sits behind a loom and hand ties individual knots onto the vertical strings seen on the backside of a rug.
Rugs made using a hand-operated tool that tufts strands of fiber through a canvas that is stretched over a frame. When the design is complete, the canvas is removed from the frame and glued to a fabric for the rug backing.
Rugs woven either on the hand, or hand and foot power-loom. To determine if the rug is hand-woven, look at the back of the rug near the fringe; if the ridges run parallel, the rug is hand-woven.
