Rugs as language, two groups with a Kurdish Accent.
Over the years I have assembled a theory that weaving is a form of language. That closely related languages will share similarities in diction and grammar and that rug weaving groups follow the same pattern with weave and structure which is the diction and grammar of this non-verbal aspect of language. Two closely related groups are the Sanandaji (Sine'i, Sina'i, Sineyi) and the Garrusi (Bijari). I pulled a few examples that show enough detail that someone might see what I am saying. Why do they use eccentric wefts? It is because that is their language. See Bijar Shahsavan kilim, circa 1900, Senneh_kilim_late_19thC and Senneh Rugs: Senneh Kelim with close-up of weave.
