An old myth within the striped rug evaluation world was that the knots per square inch would determine the value of a handmade striped rug. As a general rule, many of the striped rug districts that loomed the tightest knotted products were regions that made the same design with the same colors one after another. Every loom in the region would in essence be knotting identical in various sizes. Therefore, because of the lack of innovation, and the incredibly low wages, this was often an inaccurate yardstick. The quality of the wool, the quality of the dyes and the flow of colors and design often is a more accurate judge of value of a striped rug.
