Persian knots matches asymmetrically around of pair located beside with each other strings of a basis; the pile yarn twists one string of a basis entirely, and the second – only half. Other names of knots of this type are: farsibaff, senneh knot named after the Persian city of Senneh (now Sanandadje in the Iranian Kurdistan) and asymmetric knot.
Turkish knots symmetrically match around of pair a line of the located strings of a basis; both strings of a basis are completely twisted with a pile yarn. Other names of knots of such type: turkbaff, gyordes knot named after Asia Minor city of Gyordes and symmetric knot.
