My old mentor said to cut my grain wrong on purpose, and it took me 3 years to get it
Was shooting the breeze with the guy who taught me to bind down in San Antonio last month, and he asked why I always fight the grain on my endpapers. He said he cuts his grain short on every case binding on purpose so the boards bow toward the text block instead of away, keeps the cover flat on the shelf. I tried it on a 300 page rebind last Tuesday and the thing sits dead flat now, no cupping after a day in my humid garage. Anyone else cut grain against the book on purpose, or am I late to something everyone already knows?
