Take a look at this book. It measures 9×12 inches and has 192 pages. The paper is 60lb drawing paper and will handle just about any media. The cover is stiff smooth black cowhide. Features a flap and strap closure. The binding is a  longstitch with linking and a keyhole cut into the spine. I have a lot more pics on my flickr page. This one is sold (custom order) but I’m working on another in golden yellow deer hide.
