This is a book cover for a paperback book. For reference, the book used in the photos is 17.3cm tall, 11cm wide, and 1.3cm thick (see image 6). The front uses two types of Kurume-ori fabric. The back is black Kurume-ori. Interfacing is applied. Height: Approximately 18cm Width: Approximately 30cm when open Bookmark string is not included. Although carefully finished, this is handmade by an amateur. Thank you for your understanding. I hope someone who doesn't mind the small details will use it daily.
