As fewer Tribal peoples live nomadic lives and the same
with living in tents or yurts, tent bands are becoming more and more scarce! The dimensions of this piece tell us it was made to secure and decorate the tent struts near the mid-level of the walls. It is flatwoven of wool and goat's hair using a weft-float  and standard khelim techniques. Some of the materials are 'natural' or undyed, some dyed with natural dyes (including aubergine). 
In excellent condition with only minor  nicks from usage. The details pictures show close-up views of front and back sides.
