My first dilemma: After a decade of post-bound, did I want to switch to 3-ring or D-ring? There are pros and cons, but after looking at a variety of brands of ringed albums in person, I knew they were not for me. The main reason? A 12x12 post-bound album is already too deep for most of the bookcases we own and the ringed binders add an extra 2-3 inches of depth.
My second dilemma: What should I buy as a temporary stop-gap to hold the increasingly-large pile of layouts that needed a home? I ended up buying the absolute cheapest post-bound solid-colored album I could find, figuring that if I didn't like it, it wouldn't be too expensive a mistake. As it turns out, you do get what you pay for when you buy a really, really cheap album. It's holding layouts for now, but I'm guessing it will have to be replaced sooner or later. No more of that brand.
With fingers crossed, I tried another of the low-priced albums, this one by Colorbok.
At $13, it was totally affordable and the quality was pretty good. Not top-notch, but perfectly fine for my purposes. I bought four more. I have filled two of them and just put the post-it flags into my third using my usual system.
I should be good for another two years or so with what I have.
