This is a set of four handmade sashiko embroidered coasters. They are embroidered with off-white sashiko thread on navy blue fabric and navy blue sashiko thread on white fabric. Each coaster features a different pattern. The back of the coasters is navy blue fabric with stripes. The size is approximately 9-9.5cm per side. I make them with care, but there may be some slight imperfections such as puckering or distortion. I appreciate your understanding and look forward to your purchase.
