Baluchi tribes live in black tents. Their rugs are woven on horizontal (flat) looms. There are several different tribes of Eluchi with different names. The principal colors used are three shades of dark red, two shades of blue, tan or brown, with tinges of ivory and other colors. The color effect generally is that of dark, somber red, mahogany, wine or brown. Up until World War II, all Balouchistan came with woolen warp, and had a wide kilim effect on each end. Today many of these are being made with cotton warp, which makes for a straighter rug that will lie flat.
