Learned a hinge trick the hard way at a library repair workshop
Last month I went to a hands-on book repair session at the downtown library and watched the instructor fix a cracked hinge with just wheat paste and a strip of Japanese paper. They said it holds for decades if you let it dry under a weight for 6 hours, not the 2 I was doing at home. I tried it on a 1940s novel that had a loose board and now it opens flat without any creaking. Does anyone else skip the expensive hinge tape and go straight to paste and paper?
Wheat paste and Japanese paper is the real fix. Tape is for people who want a quick patch that yellows and fails in five years. That 6 hour weight thing is no joke either. I did 3 hours once on a 1950s hardcover and the joint puckered up like a raisin. Wait the full time, weigh it down, walk away.
