PSA: My book spines went from floppy to firm after switching to a specific PVA mix
For years, my case bindings had a slight sag after a few months on the shelf. I started adding a 20% methyl cellulose mix to my standard Jade PVA about six months ago, and the difference in spine rigidity is night and day. Anyone have a different additive ratio they swear by?
