Thank you for viewing these handmade coasters. These coasters are made with Japanese fabric and feature sashiko stitching. The backing fabric is Kurume Kasuri. They are three-dimensional and can be used as wall decorations. They are also a bit large, so they can be used as a vase mat. They may be slightly unstable if you place something light on them. As they are handmade, there may be some slight imperfections and uneven stitching. Please refrain from purchasing if you are sensitive to such details. ☆Size☆ One side of the square: Approximately 13cm~13.5cm
