Front: Uses indigo-dyed cloth that has transcended time and hand-woven scraps. Back: Indigo-dyed cloth and sashiko stitching along the pattern of a yukata. Three-layer construction with quilt batting in between. It's a little large, so it's not just for coasters; it's reversible so you can also use it as a mat for small items. Size (approximate, measured by hand): 13 cm square Please check the profile. Thank you for looking at my work from among many others.
