I found this bolt of fabric while cleaning out my parents' house, tucked away in a box at the back of the closet. I gave it a quick look and don't see any stains. It was purchased at Mitsukoshi Nihonbashi. Warp: 100% silk Weft: 90% wool, 10% nylon This item has been stored at home for a long time, so please refrain from purchasing if you are concerned about minor details.
