A retired binder in my shop said something about grain direction that made me rethink my whole process
I was showing a finished journal to the retired bookbinder who rents a corner of my workspace, proud of how flat the pages laid, and she flipped through it and said "it opens nice, but you fought the grain the whole way, didn't you." She wasn't wrong. I'd used a long-grain paper short on the spine because it trimmed cleaner, and she pointed out that's why the boards warp a little after a week in a dry room. It hit different because I'd been blaming my paste for months, not my paper choice. Now I'm laying out every signature against the grain before I even cut. Anyone else had a paper fight them like that and not notice for ages?
