Sorry that this is not the most thorough tutorial for bookbinding, but the original tutorial really has all you really need to know. I thought I'd just share the little bits that I do that might be different from the original.
One of the things I've found that simplifies everything is that instead of folding the cover over the cover guide (left) with my fingers, then folding the wax paper over and clamping it all in place, I grab the wax paper and fold it over to clamp. I end up not handling the glue areas at all, it makes everything tidier and more accurate.
When assembling the cover I've taken to gluing the corners first and letting them dry completely. It makes for a very nice, tidy corner.
Oh, and if you want to have a ribbon bookmark, the best time to add it is when you are clamping and gluing the signatures. Just lay it on top of the glue and smooth it out. Make sure it is long enough to go the length of your pages. I leave mine quite long, they can always be cut shorter later. In this book I used a woven tape-style ribbon. I'll add beads and embellishments to it in the final steps.
This is how I put the pocket in this book:
Once the signatures were in place and glued into the inside front cover, I glued the pocket in as though it were an endpaper. Normally one would glue the last page of the last signature in to the back cover before placing the endpaper. I didn't do that (that would have meant that the pocket could not sit in as snugly as the signatures). I glued the pocket side to the inside back cover, then the paper side to the last paper of the last signature.
Once the pocket was in place, I glued in the endpaper. I made custom endpapers for this book by collecting quotes that spoke to my heart about our friend's life and situation. I wrote them all in WORD, turned them all a co-ordinating purple, made each of the quotes slightly different sizes and fonts so that, though they ran together, they can also each be read individually.
As you can see in the picture there are a lot of pieces of wax paper interleaved with pages that have glue drying.
This is the point the book is at right now. I'll let it sit under a weight overnight to dry, and I'll check on it tomorrow. It will be handle-able by then, but probably not totally dry. I can do any finishing bits at that time, then leave it under a weight for another 10 or so hours so that it is completely dry and flat.
Thanks for coming along on this journey with me. Thanks to you, too, for the comments and well wishes for our friend. She is much like an Aunt to me, she and her family have been in our lives as long as I can remember. I'll always be grateful to her for letting the boys hold her newborn lambs. They will never forget it.
