This is a set of four handmade sashiko embroidered coasters. They are embroidered with off-white sashiko thread on yellow fabric, and yellow sashiko thread on white fabric. Each coaster has a different pattern. The back is striped yellow fabric. The size is approximately 9-9.5cm on each side. I make them with care, but there may be some slight imperfections such as puckering or distortion. I hope you understand and look forward to your purchase.
