That time the spine cracked because I forgot to account for humidity
I was working on a batch of journals in my garage back in August, 90 degree day with the humidity through the roof. Didn't think twice about it. Glued up the spines, set them in the press overnight. Next morning every single one of them had a crack right down the middle. Turns out the moisture in the air messed with the drying time. Had to tear all six apart and start over. Who else has had a weather related disaster in their bindery?
