Seref Ozen (Istanbul) has very kindly sent me closeups of the embroidery on two Yomud bokche (one also appears in a thread with a Tekke coat collar). Seref tells me that these were used as jewelry bags.
These are of the Yomud bokche, which Seref tells me are used as jewelry bags.
Cok tesikur edirim, Seref Bey.
