This is a B6 size handmade book cover! You can change the design to a cute cat pattern or a simple denim design depending on where you use it! I made the original pattern for myself, but it was so comfortable to use that I made some for sale too! I hope I can share some happiness with you ♪ Note: I have a dog at home. The dog does not directly touch the product, but please be careful if you have allergies.
