This is a refined Fukuro obi
with wave and flying crane on 'michinaga-dori'(wavy line) pattern, which are woven.
Gold and silver foil threads woven on the background and pattern are gently shining.
Textile is exquisite silk and has soft touch.
It has small snags such as Otaiko, but they seem not to be so prominent.
There are rather prominent folding lines overall. May be, this piece was tied in fancy bow. (*The lines are indicated partway on the figure.)
Please check detail photos.
It has a sense of use, but it still can be tied!
Please enjoy its sophisticated fashion!
