This is a Tsumugi Fukuro obi
with flowers & birds on clouds, which is dyed and embroidered.
The dark color tone makes it chic yet elegant.
It has fine drawn works (one of the techniques of removing thread partly to make a ground textile seen through).
Textile is rustic soft Tsumugi
silk with knobs of yarns.
There is white stiff lining inside.
So that, the white lining can be seen through the drawn works area.
There are folding lines, white stains.
For the details, please refer to the photos and figure.
Although it has some flaws, none of them bother to wear.
Enjoy wearing the fashionable design.
