I finally stopped using PVA glue for everything after a book fell apart in my hands
For years I thought PVA was the only glue you needed for bookbinding. I used it for spines, endpapers, everything. Then a custom journal I made for a friend came back after six months, the spine completely cracked and pages falling out. She lives in a really dry climate, and the PVA had gotten brittle and failed. I looked it up and found out that for flexible spines, especially in changing humidity, you need a different mix or a different glue entirely. Now I use a mix of wheat paste and PVA for certain projects, and it holds up way better. Has anyone else had a glue fail because of the weather where the book ended up?
