Kilims are pileless and are produced by tightly interweaving the warp and weft strands of the weave to produce a flat
surface with no pile. Kilim weaves are tapestry weaves, technically weft-faced plain weaves, that is, the horizontal weft strands are pulled tightly downward so that they hide the vertical warp strands. They can be classed as "slit woven" textiles.
The slits are beloved by collectors, as they produce very sharp-etched designs, emphasizing the geometry of the weave.
