Saroughs are hand knotted on a vertical loom using warp and weft in cotton. The weft consists of two or sometimes three threads. In carpets made before the 1915, the weft is pushed down hard against the knots, which made the carpets very compact. The pile is of very good quality wool and is cut very short. However, more recent pieces seem to have deeper piles. The Persian knot is utilized with a density of 160 to 400 knots per square inch. Size: 5'1"x3'5"
