Conclusion
Overall I was pleased with the result. I have struggled to get binding right before, but I think Japanese stap stitch was much easier to do than I had initially imagined. I intend on using this with my actual publication. I am going to have to allow an extra 1cm bleed within the spine, to allow for the binding. I also think I may not risk double page spread images, as they could be difficult to line up.
