This is "jidai-gare," or "era-split" fabric. It's cloth made by deconstructing kimono and haori (outer jackets) with damage like burns, stains, and dirt, and taking the best parts. While it's fragile due to its age, those who love antique fabrics will find it enjoyable just to look at. Perfect for making han-eri (collars) and small accessories. ♡
