I'm redoing an album of my class reunion photos over the years. I had done them in 8.5x11 so I could print at home but I no longer have the supplies I used so haven't been able to update for the 2014 photos (deleted the kit since it was an old one without checking if I needed it). So I just decided to start over and do 12x12 to do a Shutterfly book sometime after my reunion in 2019 (#45). Each page is very basic with no elements, just photo mats and maybe another paper mat. The year is on the page as well as a designation as to what reunion it was (5th, 10th, etc.)
I have named the pages by the year with an A, B, C etc. They sort on the computer nicely that way.
For trips, I tend to use a description title with the A, B, C designation as well. Thinking back, I tend to do the alphabetic designation on many of my layouts that are multiple pages for an event.
