This is a silk bolt for Tsumugi
kimono with flower in 'kikko'(tortoise shell) pattern, which are woven with double ikat technique.
Textile is exquisite silk and has soft and fluffy touch.
Though the figure says those are patinas, those are more likely molds with ages.
It also has a little musty smell.
Discoloration can be seen on douura(upper lining) and hakkake (lower part of lining) as well.
For the details, please refer to the photos and the sheet.
It must be an amazing handicraft material!
