Recalled my old bookbinding teacher's advice about glue and finally see the point
Back in 2019, my teacher in Portland told me never to use PVA glue for book spines because it dries too brittle and cracks over time. I thought she was just being old school and stuck to my cheap white glue for two years. Then last month I opened a journal I made in 2020 and the spine had a hairline crack running down the middle. I switched to a high-quality PVA that she recommended, the pH neutral kind from Lineco, and glued up a test book six weeks ago. So far no issues, and the flexibility is way better. Has anyone else had a teacher's tip turn out to be right after you brushed it off?
