This is a Tsumugi Fukuro obi
with abstract "Karabana"(imaginary Chinese flower), 'susuki'(Japanese silver grass) and butterfly design on 'kiredori'(overlapping fabric scraps) pattern, which is woven.
It is a tasteful piece with the design against the rustic base.
Textile is light Tsumugi
silk, and not nubby touch.
It has slight folding lines, but not disturbing for wearing it.
For the details, please refer to the photos and the sheet.
There is no fatal flaw to tie it.
Please enjoy its stylish design.
