Dye-ing of the wool/silk:
The weavers sit at the loom with the balls of the individually dyed wool hanging overhead. Generally, a room size rug will have about three weavers sitting on the loom. With graph by their side, the weavers begin to pull down the wool from above and tie it around the foundation. They weave from left to right and after each piece of wool is hand tied, they clip it and move to the next. After several rows of knot tying, the weavers pack down the wool with a metal tool in the shape of a curved brush. This packing does two things: first, it assures the weavers that the knots are tight against each other and secondly, since the tool is curved at an angle, this gives the pile of the rug an angle. The result of this can be seen when the rug is complete: there is a dark and a light side to the rug. When looking at the tips of the wool, we see the dark side and the back of the wool is the light side of the rug. It is a similar idea to velvet. Once the weavers are finished weaving a rug, they have an extension of the foundation on top and at the bottom of the loom. This is where they cut and take the rug down. The result of where they cut is what determines the length of the fringe, since the fringe is actually a part of the rug.
Once the rug is off the loom, the pile is at various heights and now it goes through the clipping process. People actually get on their hands and knees and start clipping the pile several times until they are satisfied with the feel, making the pile as even as possible.
Once clipped, the rug is now ready for wash. The rug is hosed down with water and this is a good test for the colorfastness of the dyes. Once wet, the rug is then scrubbed with soap and water and a scrub brush and then hung to dry in the sun.
