This is a set of two handmade sashiko embroidered coasters. One coaster features sashiko embroidery with natural-colored thread on a pale purple-gray fabric (similar to sumi-iro, or "charcoal gray"). The other has sashiko embroidery with pale gray thread on white fabric. Both have been pre-washed and have interfacing applied. The backs are made with the same charcoal gray fabric and white fabric in a striped pattern. Each coaster is approximately 9cm on each side. I make each item with care, but there may be slight imperfections such as puckering or unevenness. Thank you for your understanding.
