This is a Tsumugi Fukuro obi
with classical design such as 'housouge'(large karabana flower), 'shokkou'(octagon and rectangle) and 'shippou'( four circles) on jigami'(fan shape), which is embroidered.
Drawn work (one of the techniques of removing thread partly to make a ground textile seen through) is added to the design.
Textile is Tsumugi
silk and has soft but nubby touch with rustic atmosphere.
Discoloration can be seen throughout both edges, and the wrong side is prominent.(A)
Besides it has a folding line, so please check photos for details.
If these flaws do not bother you, it could be still worn.
Please enjoy its tasteful fashion!
