I've been watching a lot of bookbinding videos on YouTube lately, and I thought I'd give it a go. I've done some bookbinding before, but I never really knew what I was doing — I was just guessing really. This is the first time I've actually followed any sort of instruction. In the photo it's sitting splayed out to dry overnight.
It's a very slender volume, just 48 pages (so 24 leaves), roughly A4. The text block is just a double-fan glue binding; I would have liked to try stitching it, but I don't have access to an A3 printer to make folded signatures of this size. The cover is a bradel binding, and I made the book-cloth covering from a scrap of printed cotton, saturated with a paste and acrylic medium mix to give it some stiffness and prevent glue strike-through.
The boards are 3mm grey-board. I could have gone a bit thinner I think; 2mm would have been quite adequate. They've warped a bit with all the glue, and I'll see if they settle down as everything dries out properly. If not, maybe a bit of clamping will help. And if it doesn't... well, it's not the end of the world.
