An issue I run into when setting up long-form documents in InDesign occurs when I’m establishing sections. The problem being that starting a new section bumps the first page of that section out of its current spread. That’s no good at all good sir (or madam)!
As is normally the case, the solution was quite simple. You need to deselect Allow Selected Spread to Shuffle in the “Page” panel contextual menu. I recorded this wee tutorial that shows how to do just that. Thanks for watching!
