So I'm looking to try my hand at bookbinding from scratch, from printing and folding signatures to attaching wooden boards for the covers, to tooling and connecting the leather binding to the wood. The book that I want to bind is planned to be 8-1/2 by 11inch after folding the signatures, thinking about trying to find some 1/8th inch boards for the covers,and I'm planning on using 1inch leather strips to bind the signatures to and then glue the strips to the boards. I also plan to have a serious amount of tooling to do on the leather. I'm curious about what extra leather I should have around the edges, any recommendations or critiques would also be helpful.
