"Sennah Baft" or Hamadan Rug Weave

Single weft is called "Sennah Baft" or Hamadan weave. Here the wefts are rigid and the warps are sinuous. As you can see in the sketch the wefts are heavier than the warps. It is woven with symmetrical knots. Since there is only one shot of weft between each row of knots this shows every other warp which makes these rugs easy to spot.
