binding

staples
the book is not to be mass-produced, so this does make that much sense. Also, there are too many pages for it to be folded and trimmed nicely without the pages losing large amounts.

perfect binding
with the images being centred and going across the spread, it would be nearly impossible to ever see the full image when reading the book.

pamphlet stitch
Like the staples, you would lose large bits of the book when trimming it down.

Coptic stitch
kettle stitch
To have the book lay flat, it would have to be stitched with a Coptic stitch or kettle stitched. the problem is that this is quite difficult to attach, but it can be done

Hardback is quite an easy implementation to any bookbinding. You need to cover it with whatever the cover is to be and properly measure the distance that the book takes up. here it had some issues as the fabric folded quite thick, so I had to make 6 covers before getting it right.  with kettle stitch, you have two main options glue in the spine, I did that last year, and it leads to the book not laying fully flat, the second option is to glue one or two sides of the signatures

There could be several ways of archiving a binding that would work for a thicker book, such as perfect binding, Coptic stitch, tape stitch and kettle stitch, all except for the perfect bound one uses signatures and several sections to make up the book. They are attached similarly to pamphlet stitching., but with several sections. Kettle stitch with tape is based on having a basic kettle stitch but binding it to the tape so that the cover can be attached with them instead of glue endpapers or the spine. Coptic binding is based on being attached to a hardcover. The spine is traditionally exposed, and that makes the book lay flat really easy. The last binding method is kettle stitch, where you bind each section to the last one. Creative kettle stitched books usually have exposed spines, but the commercial one’s books usually have it covered.
