I know others have posted things like this, but I finally got around to just compacting my collection - I was getting tired of having to pick and choose which expansion to bring to game nights, and always bringing Hinterlands because that's where I shoved the pretty Base Cards. I actually got this idea from...
I want to say Voltaire? I don't remember exactly, but it was a dude-man from here that I was Skype-playing with, and he had everything done this way. probably either BeyondAwesome or Chris is Me, my memory is apparently terrible.
The basic idea is you get pocket pages - you know those plastic things you may or may not have stored Pokemon (or hell, probably even MTG) cards in? Just get, like, 30 of those. Each pocket (9 per page) can fit stacks of 10-12 cards quite comfortably, and you can even shove Rats and the Events into pockets and they'll be fine. I got Ultra-Pro pages because that was literally the only thing they had at Walmart (seriously, it was just one pack of 35, shoved under some homework folders next to the Scotch tape, it was weird). My one concern is that with the regular 3-ring binder, you have to be careful not to tilt it upside-down, or cards might start slipping out. My next step will probably be to get zip-up binders to protect against that very catastrophe.
Anyway, here's some pictures, and thanks!
Voltaire people... I think.
Also - I've ordered things in wiki order - by set, by cost, then by name. Non-supply cards are stored next to their parent cards (if there's only one), and at the beginning or end of a set if used by more than one card, along with expansion basic cards (Shelters, Platina, etc).
Before:
After:
Shove all those mats and tokens and shit in Hinterlands with the basic cards (don't carry spare base cards, because fuck 5/6 player games):
Nice and tidy and compact:
