Hand Knotting is the oldest method of weaving rugs. Two to five weavers sit side by side facing the rug and work in harmony to complete each section. They tie yarns onto the rug backing forming lines of knots.
The knots can be tied smaller or larger depending on how intricate the design is.
It is important to look at the length and luster of the fiber, not the thickness of the rug. If you view the back of the rug you will be able to see the same pattern as reflected on the front.
These rugs are very time consuming to make. It usually takes 4 to 5 weavers 3,000 hours to complete a 9' X 12' area rug.
As you can imagine these rugs are expensive but they are well made and will last a life time.
