This is a blank book made as an experiment. It measures roughly 5" x 7". The pages and flyleaves are a heavy art paper that I have a huge box of; its exact nature is unknown. The cover boards are made of cardboard covered with 4 oz. leather. The three sections are sewn onto cords of common twine. The spine is reinforced with strips of linen, and everything was glued together with wood glue. The sections are sewn together with silk thread.
The first and last pages ended up getting glued to the covers, which was not my original intent. In the future I would add another leaf when binding to attach to the covers. I would also use a thinner leather.
