These rugs were not made for survival by the Navajos before the 15th Century. These rugs have become one of the most important decorative items in households. The Navajo rugs are luxurious and costly because of a variety of factors. Here are some common reasons why these rugs are so expensive. Contrary to other types, weaving rugs is more difficult than the others. These rugs use handlooms, which can be operated manually. Back then, weavers set up their weaving looms between two trees. Nowadays, weavers use poles rather than trees. They sit on small tools or on the floor while weaving on their looms. For a perfect base design, weavers often overlap the threads multiple times. Then they add layers of other designs. They are commonly known for their distinctive patterns, which allow people to recognize the rugs. You can clearly tell the difference between Navajo rugs and other types of rugs if you look at the wool and fabric. Hand-spun wool was made by the Navajos from their own sheep to be used on the rugs. They used Saxony, a silky, naturally tinted yarn.These rugs are made with all-natural ingredients, which guarantees the high quality of the Navajo rugs. It was also hard to spin these wools, making them so costly because of the tedious work and effort required by the weavers. Unique designs made the Navajo rugs unique and special.
