This is a vintage Maru obi
with tranquil tiny 'karabana' (imaginary flower in china) pattern, which is woven.
Textile is silk, and it has soft touch.
Length is 396cm(13.06ft), rather short for Maru Obi.
Kaikiri line on the wrong side are coming loose.
Both edges are smudged and fabric seems weakened. (sorry no photos)
Folding line continue from Tesaki to Tare end, but it is light.
It has some other flaws as shown on photos.
Please see photos for details.
Because of the flaws mentioned, it is no longer suitable for wearing.
It must be an amazing handicraft material!
