This is an attractive Tsumugi Nagoya obi
with a lovely flower and bird on circle design, which is embroidered with fine Sagara embroidery work.
Drawn work(one of the technique of removing thread partly to make a ground textile seen through) is added on otaiko(square bow) and gray lining can be seen through.
Textile is Tsumugi
silk and has soft, but nubby touch.
Though indicated as dyestuff, it seems to be whitish rough sketch, and can be seen on otaiko(square bow) and 'Maegara' (front patterned part) beside indicated.
For the details, please refer to the photos and the sheet.
It's still wearable enough in very good condition.
This refined piece will brighten up you on the scene for sure!
