Knot density could be a factor in the value of a rug, but this is not always true. In nomadic and some village items, knot density is usually not a factor. It is not a factor for collectors of these rugs either because nomadic and village rugs are judged by different standards than workshop rugs. Nomads and village groups do not have the same sophisticated tools as other city weaving groups. Their items are valued by the fact that their designs are created from memory, their dyes and materials are provided from the nature around them, and most importantly the weavers’ way of life is expressed in them
These rugs generally have a knot density of between 25 to 100 knots per square inch. Rugs with higher knot density take a longer time to make, and since nomads migrate as the seasons change, if their rugs are not finished in time for migration, they will have to carry the looms with them.
Therefore, their rugs tend to have a lower knot density than workshop rugs. The value of these rugs lies in their heritage and simplicity. They have artistic value.
