I don't consider myself a person who tends to do a particular kind of page, one or two page. I choose the number of pages based on the number of photos I have. When I have many photos, especially ones I can't trim much, I make two pagers.
How do I make them work? I have a few tricks:
Line them up. I see nothing wrong with doing the easy thing: line up photos across the pages to add cohesion. I do it evenly
Cut the photos the same size. This makes them easier to grid, like I did here (I think I trimmed them 3 1/2 x 5).
Don't use a focal point photo. This might be sacrilege, but if I am scrapping an event, and there is not one significant photo, why do I need a focal point photograph?
I'm sure I have some more tricks with creating two page layouts, but these are some principles I follow to design two pagers. Works for me.
