The surface is sashiko stitched with a small flower pattern. The back uses soft, organic cotton. The sashiko stitched surface is made by layering two layers of bleached cotton, resulting in a sturdy finish. It can be used as a coaster, of course, but also as interior decor! It's also great for holding accessories or small items. Size: Approximately 12cm x 12cm I designed and embroidered the pattern myself. I used a friction pen that disappears with ironing for the initial sketch. I have ironed the sketch away after creation, and so far, there are no visible marks. However, if any appear, they will disappear with ironing. Thank you for your understanding. Each item is carefully handmade, and I appreciate your understanding that it is a handmade product (*^^*) #handmade #coaster #sashiko
