Tirmeh is a fine textile already made in Safavid Persia (16th -17th century). The very soft belly wool (kork) of young sheep is used to weave these very thin shawls and fabrics.
The weft is passed over two warp threads, creating a kind of herringbone pattern.
The technique is quite like that of Kashmir shawls, as well as the material and boteh motifs.

Sources often contradict each other when tirmeh is discussed. Some claim that under the Safavid era, the fabrics were imported from Kashmir (or if not the finished fabrics, at least the materials: pashmina wool). Others claim that they were traditionally manufactured in Yesd (Persia), where the kork wool equalled the pashmina in fineness.

Pearls and silver thread were also applied to some tirmeh. This processing is called sermeh doozi.

In the Encyclopedia Iranica P.836, vol V Azeri garments are described as follows: …Cut velvet, gold brocade and a striped woollen twill cloth (tirmä) were characteristic of the finer garments, all trimmed with decorative braids and often with silver or gold lace at the cuffs.
