Nambu Sakiori Retro Mat 35cm x 185cm

This is a very old tsutsure-ori (rag weaving).
I purchased it at an antique shop in Morioka about several decades ago and kept it at home.
It appears to have been used regularly, as the edges were folded and sewn. I recently removed the threads and hand-washed it to remove dirt.
Please check the photos as there are color variations between the front and back.
As it is an old item, brightly colored fabrics were not used.

Thank you for looking.
