This refers both to the carpets made in the sumak technique and the technique itself. Primarily practiced in the eastern Caucuses, this technique produces a flat-woven carpet using weft wrapping in which wefts are pulled over then wrapped under a series of warps.
* Warp - The longitudinal threads fixed to the loom before weaving begins, which form a basic part of the structure.
** Weft - (also WOOF) The threads which are added in succession to the warp, crossing at right angles in the direction of the width of the fabric. In piled carpets they are invisible on the surface in kilims the wefts are the only threads visible.
