All natural colors very colorful collectable kilim, about 40 years old.

Because kilims are often cheaper than pile rugs, beginning carpet collectors often start with them. Despite what many perceive as their secondary (or inferior) status to pile carpets, kilims have become 
increasingly collectible in themselves in recent years, with quality pieces now commanding high prices.

What some sensed as inferiority was actually a different nature of rugs woven for indigenous use as opposed to rugs woven on a strictly commercial basis. Because kilims were not a major export commodity, 
there were no foreign market pressures changing the designs, as happened with pile carpets. 
Once collectors began to value authentic village weaving, kilims became popular. Now, many kilims are woven for export. Kilims 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. When the end of a color boundary is reached, the weft yarn is wound back from the boundary point. Thus, if the boundary of a field is a stright vertical line, a vertical slit forms between the two different color areas where they meet. For this reason, most kilims 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. Weaving strategies for avoiding slit formation, such as interlocking, produce a more blurred design image.

The weft strands, which carry the visible design and color, are almost always wool, whereas the hidden warp strands can be either wool or cotton. The warp strands are only visible at the ends, where they emerge as the fringe. This fringe is usually tied in bunches, to ensure against loosening or unraveling of the weave.
