This year I am switching things up a bit and downsizing to 8.5×11 pages. I figured 9×12 supplies would be harder to find, and since me and Photoshop are pretty tight, adjusting PL templates to fit 8.5×11 was no big deal. They aren’t standard 3×4 & 4×6 size slots, simply because the math just doesn’t add up. But I am quite content with them and I hope fewer slots will help me to keep things simple this year!
EDIT: I ended up revising this decision and switching to 12×12 for simplicity’s sake.
