Thank you for viewing my handmade coasters. These coasters are made with Japanese fabric and sashiko stitching. The backing fabric is Kurume kasuri. They are large enough to be used as a vase mat. They are three-dimensional and can be used as wall decorations, but they may be a little unstable if you place light objects on them. As they are handmade, there may be some slight distortions or uneven stitching. Please refrain from purchasing if you are sensitive to such imperfections. ☆Size☆ One side of the square: approximately 14cm
