The technique of making this type of kilims involves wrapping wefts over a certain number of warps (usually 4) before drawing them back under the last two warps. The process is repeated from selvedge to selvedge. The wefts are discontinuous; the weaver selects coloured threads in turn, and wraps each within the area which is to have that particular colour. Unlike kilim, the back is left ragged, with all the loose ends of the differently-coloured weft threads visible, sometimes several inches long, providing extra thickness and warmth. Also unlike kilims, there are no slits where colors meet.
