This is a set of three handmade sashiko embroidered coasters. The embroidery is done with black sashiko thread on a dark gray fabric. The embroidery has been washed and interfacing has been applied. The backs are made with black and white striped fabric, black fabric, and natural-colored fabric. Each side is approximately 9-9.5cm. I make them with care, but there may be some slight imperfections such as puckering or distortion. I appreciate your understanding.
