This is a fashionable Tsumugi Nagoya obi
with abstract pattern which is woven colorfully.
Textile is rustic Tsumugi
silk, and it has soft but nubby touch.
Other than prominent folding lines (1st photo), it is covered with patinas and discolorations.
Please check photos and a figure for details.
It won't be tie-able since discolorations and patinas are disturbing.
However please enjoy this rustic Tsumugi
fabric to handicraft materials!
