This is a set of a handmade sashiko embroidered pot mat and two coasters. The embroidery is done with gray sashiko thread on beige linen fabric, which is then combined with gray linen fabric. The pot mat has three layers of quilt batting, and the coasters have interfacing. The pot mat measures approximately 12.5 x 13.5 cm, and the coasters are approximately 9.5 cm on each side. I make each item with care, but there may be slight imperfections such as puckering or distortion. Thank you for your understanding and I look forward to your purchase.
