There are two kinds of knots used in handmade rugs. The double knot, also known as the ‘Turkish Knot’ and the single knot, also known as the ‘Persian Knot’. Turkish Knot is a symmetrical knot and in Anatolia it is also known as ‘Ghiordes Knot’. Turkish Knot is used in rugs made in Anatolia, Caucusus, Azerbeijan and North East Iran.  Turkish Knot is wrapped around two warp lines symmetrically, pulled out from the middle, tightened and the ends are cut. This way the knot is wrapped around two warp lines forming a solid structure.
