Maybe you can't find what you are looking for, maybe can't even find something you like, either case here are some ideas to make your own design/ pattern paper...
This book is almost fully made using recycled materials, probably close to 95%. The paper for the text block is made from old newspapers, the cardboard for the cover comes from an old book, which otherwise would have been discarded. The only new materials used are the kraft paper for the cover and the fabric for the spine.
