I noticed that the box border of figure 2 was somewhat similar to the border of my Milan bagface and it reminded me of similar borders seen in Sauj Bullaq rugs and discussed last millennium during my second Salon . Their foundations are almost always wool. Their wefts are usually two-plied yarn. Colors will range from ivory through all shades of natural brown, and will include dyed colors in various red, blue, and red-brown shades. Undyed goat hair is also sometimes used.
Edges are almost always multiple warp cords overcast with a single color of yarn.
The structure is flat, without any depression. Usually there are two weft shots between the knot rows, although there are also bags with occasional weftings of four or more shots. Beyond these routine observations, however, there is a very interesting technique that sets these Kurdish pieces apart from pile weavings of most other provenances. In order to achieve the smooth diagonal sequences of their diamond designs, the knots in their fields are invariably tied on alternating warps instead of being stacked in vertical rows as in other weavings. Except for the type of selvages, William Eagleton and Mark Hopkins agree about the basic technical parameters of Jaf bagfaces.
