The one thing I see new binders skip that ruins the spine

I was helping a friend rebind a cookbook from 1975, and she glued the text block directly to the cover boards without rounding and backing first. Now the book won't open flat and the spine is cracking after just a week. How do you explain why that step is so important to someone just starting out?

My first bookbinding project had the same problem.

Honestly, the glue situation is half the battle. I spent my first project using the wrong kind entirely, and the pages just slid out like a deck of cards. It was less a book and more a sad paper sandwich. Had to go back and learn about grain direction, which felt like a whole other hobby.

Read this old article comparing a book spine to a human backbone. It said if you just glue it flat, it's like trying to run with a stiff, straight spine, you'll just break something. The curve from rounding gives it that natural flex, so the pages can fan out without pulling on the glue. Your friend's cookbook is cracking because every time she tries to open it, that stiff spine is fighting against the hinge. The curve isn't just for looks, it's what lets the book move.
