There are two different kinds of knot employed, the Ghiordes or Turkish, and the Senne or Persian. In carpets made with the former, the tuft of yarn is knotted round a pair of warp threads in such a manner that the two ends of yarn come between the two warp threads round which the tuft is looped, and consequently two pile ends alternate with every two warp threads. In Persian carpets the tuft is knotted in such a way that one end of the tuft obtrudes between each warp thread. This method of weaving renders possible a closer texture than the Turkish knot; while carpets of suitable design and finer pitch are often woven with a running thread looped round the finger of the weaver, and then cut, instead of by individual tufts. This latter system gives more waste but quicker weaving. With both Turkish and Persian knots the tuft ends do not stand up at right angles to the plane of the fabric, but lie over obliquely towards the starting end of the carpet. This natural slant of the pile, which results in presenting to the eye and the foot of the user of the carpet partly the ends and 안양오피 partly the sides of tufts, is a very characteristic feature of hand-made carpets, and one which cannot be completely imitated by any class of machine-made fabrics.

Another kind of hand weaving is the tapestry method, wherein the weft colours, wound upon wooden needles, are threaded round and between the warp ends, leaving a flat or slightly ribbed surface, not unlike that of an ingrain carpet. The absence of a tufted pile does not make this a luxurious carpet; but it enables a fine pitch to be employed, and the richest and most delicate effects of design and colour to be obtained. Carpets of this type have long been made at Les Gobelins, Paris, Aubusson, and Beauvais, in France, and Tournai, in Belgium. The work is slow and highly skilled, and the product is naturally very expensive.
