The intended use is flexible, but I believe it's a kotatsu cover. I considered throwing it away, but the design is lovely, so I'm offering it for sale in case someone would like to use it. This belonged to my grandmother, who is from the Showa era, so it's quite old. It's square, 190 cm by 190 cm. It's folded, so it's thick, but it's made of thin fabric for summer use. There may be some minor scratches and stains, but there are no holes in the fabric, so it's perfectly usable. Please purchase it if you like it.
