This is a Tsumugi Nagoya obi
with elegant flower design, which is embroidered with sagara(weave like tiny balls).
Drawn work(removing thread partly to make a ground textile seen through technique) is also used and ocher-colored lining is be seen.
Textile is knotted Tsumugi
silk, but has soft touch.
Drawn worn embroidery is on one side of maegara(front design).
But if you start wrapping the obi from your right tummy to left(rotate obi counterclockwise), it will be shown.
Although there is no figure and photo,
from tare(wide part)-end to tare-top(triangle part) is slightly discolored.
Also it has some folding lines(it will be hidden when tied), so please check figures and photos for more details.
It's still wearable enough with very good condition.
Please enjoy its elegant design!
