I had a few people ask me about the Coptic endbands after my
previous post. I answered a couple of emails, responded to an inquiry through Flickr and just now also in the comments here on my blog. So, I'm going to post about it again and maybe answer questions for a few other people too.
I have seen instructions for sewing Coptic endbands in just one book, "Making & Keeping Creative Journals" by Tourtillott. I found the instructions difficult to follow, and I'm not sure that I actually ended up doing it quite the way it was described, but I had some success with it. There may be a better resource - if anyone has a suggestion - please share. Edit: "Headbands: How to Work Them" by Jane Greenfield is apparently a better resource! thanks for sharing that, Marloes.
One of the other questions was, would these endbands help stabilize the book's spine and prevent it from skewing diagonally. The short answer is, Yes. And if this kind of skewing is a problem for you, keep in mind that this kind of chain stitch binding is not well suited to big or thick books. So if you are making a really big and thick book with many signatures, an unsupported and exposed chain stitch is not a good choice. On the other hand, when used on a smaller slim book, the unsupported, exposed, chain stitch could be perfect!
This question also led me to my bookshelf, to refer to Szirmai's descriptions of the early and late Coptic bindings because I seemed to recall that these bindings were not really meant to have exposed spines. In his description of the early multi-quire Coptic bindings (pre 7th Century), Szirmai describes one example which had leather strips pasted across the spine, then a larger piece of leather pasted over the whole spine surface, obviously completely covering the chain stitching. And in the later Coptic bindings, Szirmai writes that the chain stitch bindings of that period had cloth pasted to the spine for stability. Usually a coarse blue cloth, pasted directly onto the spine and extended on both sides and pasted to the outside of the cover boards.

Here is a beautiful example of a leather-covered spine, from Kaija,
Paperiaarre. Thanks for finding that perfect example for me, Astrid!
To some, it may seem crazy to cover up the beauty of a well-formed chain stitch, but if a book is meant to be durable and reliable, then having a binding that is functional and effective should be more important than having an exposed spine. As always, I keep ranting about structures. So now I'm wondering, what's my point? We just need to keep this stuff in mind when designing books. All the different elements have to work together. And if a binding needs support, then support it.
