Sometimes known as the "Cadillac" of Navajo rugs, the Two Grey Hills is a bordered rug and utilizes natural wool tones of white, brown and black. No commercial or vegetal dyes are used except for the black color.
One of the characteristics of a fine rug is the light weight accounted for by extremely careful carding and spinning resulting in a high thread count. A weft (the threads running across and woven into the warp threads that hold the piece on the loom) count of 50 per inch is a high quality rug. A count of 80 or more qualifies a rug as a tapestry. Some outstanding Two Grey Hills tapestries have counts of 120 or more.
