It’s a common request, and it’s not too hard to manage with a little trick.
You want an object or text to look one way on a left page, but look different on a right page? Blatner shows how you can achieve this “impossible” task.

Sometimes you learn something that is new to you, but obvious to others. I compiled a list of things I have learned in the last year that I probably should have known.
