Rows of knots
are tied on a foundation of warp and weft and become the pile, which consists of upright yarn. The warp runs along the length
of the carpet and the fineness of the weave depends on its thickness and the proximity of the warps to one another. When the
rug is completed the ends form the fringes, which may be weft-faced, braided or tasseled or secured in some manner.
There are two basic types of
knots, upon which variations are based.
- The Turkish
knot, which is typically single-wefted or symmetrical
- The Persian
knot, which is typically double-wefted or asymmetrical
The higher the knots per square inch
(KPSI) the higher the quality. Our rugs run from 500 to 1400 KPSI.
The warp and weft of a carpet
can be various combinations of wool, cotton, silk, and these materials themselves come in various qualities and textures.
