The information shared so far is extremely helpful. Thanks! I especially appreciate the spine calculator because I know I always overshoot the size. I think anything I share at this point will become redundant, but I will add to the list of videos and instructions out there for making perfect bound books. On Skillshare, I was able to access fairly detailed instructions/videos on the process.
I also found this site by a printing company in the U.K. to be informative: ExWhyZed. There's info on everything from how to set up the file to binding, stitching, paper options and sizes. They're too far for us to use, but the resource page is still helpful.
