Oshima Tsumugi (silk fabric) Size: 11cm x 12cm Slightly crisp with a sheen. Same fabric used for front and back. No interfacing. Edges are stitched with a 2mm stitch. Remade from a kimono into a coaster. This is an old kimono that hasn't been used yet. I finished it carefully using my sewing experience, but please forgive any imperfections such as slight curves.
