This is a casual Tsumugi Nagoya obi
with vibrant stream design, which is roughly woven.
Textile is exquisite Tsumugi
silk and has soft touch with rusty and warm atmosphere.
It is sewn as "matsuba-shitate" (open Nagoya obi
with tightly folded end of belt part).
It has slight discoloration on its base.
It also has folding lines and discoloration like stains beside the 'Maegara' (front patterned part).(A)
It seems to be discoloration of the warp yarn, and when you start wrapping the obi from your right tummy to left(Rotate obi counterclockwise), it will be hidden.
Though it has some flaws, please enjoy this impressive piece as everyday clothes.
