Iranian and Oriental rugs whether made in tribal or city surrounding are all hand knotted, the weaver ties the material (whether it be wool or silk) around the warps of the foundation using one of several different knots. Each rug is made to a design, whether that design is copied from an intricate design plate or is inspired by the weaver, their surroundings and their way of life depends on the type of rug.
