I made this with fabric to be as light as possible when carrying it around, such as when going out. It's reversible so you can use both sides to avoid getting tired of the pattern. Book cover size (for paperback books) This is a handmade item, so there may be imperfections such as stitching lines and slight distortions. Please understand. m(_ _)m * There may be differences in color between the image and the actual product. Thank you for your consideration.
