I swore by PVA glue for years until a rainy week in Portland changed my mind
I was rebinding a 1920s poetry collection for a client and the humidity made the PVA take forever to set... it was a mess. An older binder at the local shop, Maria, convinced me to try wheat paste for the spine lining. The flexibility it gave the text block was a total game changer for that old, brittle paper. Anyone else switch adhesives for specific projects like that?
