Wrote off leather spines after a bad batch, then a repair job in Tulsa changed my view
I stopped using leather for spines about 3 months ago after a batch cracked along the joint on 4 of my own notebooks, and I put it down to cheap hides. Then last week a customer brought in her grandfather's 1930s bible with a torn spine and asked if it could be saved, and I told her leather was risky. She said to try anyway, so I pulled some veg tan I had sitting on the shelf and rebacked it in about 2 hours, and that spine flexed fine with no cracking at all. Turns out the issue was how thin I was paring the leather on those earlier notebooks, not the leather itself. Anyone got a go-to thickness for spine leather on small books? I was working around 0.6mm on this one.
