Diane, I'm not going to say "did you really go there" cause I thought the same thing.

I was actually a little worried that all AA's stuff wouldn't fit given her description of her list!
We don't just "throw things in there" either. There's a definite method to my packing, with things that go in the bathroom and bedroom (for the most part) in one and things that go in the kitchen or for general use in the other. Then I loosely prioritize so that the things we might need quickly are on the top or close to it. We don't throw in loose coffee filters (they're in the package) or loose Band-Aids (again, in the hard plastic container they came in). I saved the plastic packaging for my good knife and put it back in that for storage. Most medicines and small items are in the tackle boxes. Some small items with no package (like sugar packets) go inside the Brita pitcher or in one of the 2 sandwich-sized storage containers I have. There's nothing even remotely like the bottom of a kid's toy box about our lockers.
One of the reasons I got a second locker was that after filling the first one the first time, it was so heavy I couldn't lift it on my own. AND it had that tell-tale bulge in the lid when closed, and I knew I wasn't "done" stocking it yet! So now one closes easily but is very close to full and the other required sitting on, but only because of the fleece blanket, which compresses easily. (i.e., my string bean skinny son sat on it, not me or my husband, and that was plenty of pressure to close it)
The other nice result is that now I'm not stressed about everything fitting, even if we add a few items here and there.
