Unpopular opinion: I stopped using wheat paste for book cloth after a conservator set me straight
She told me, 'You're not making papier-mache, you're binding a book,' and showed me how wheat paste causes long-term warping. Has anyone else had to unlearn a go-to method after getting real feedback?
Actually PVA isn't ideal for book cloth either. Needs to be a flexible adhesive like Jade or pH-neutral PVA, regular PVA gets brittle and cracks the spine over time.
