I still use animal glue for spine lining and I don't care what anyone says
Honestly, everyone acts like PVA is the only way to go now, but I had to pick between that and traditional hide glue for a big rebind job last month. I went with the hide glue, the kind you have to heat up in a double boiler. It was a pain, sure, and my shop smelled like a barn for a day. But the flexibility it gives the spine as it sets is just different. I did a full leather binding on a 1908 poetry collection, and that spine moves like a dream. A guy at a meetup in St. Louis told me I was wasting my time and that modern stuff is stronger. Ngl, maybe it is, but for a book that's meant to be opened and read, not just sit on a shelf, I think the old way works better. Has anyone else stuck with animal glue for specific jobs, or am I just being stubborn?
