I just found this thread, lol. So: Necromancy time!
Like Acadian, I keep my Alliance War stuff all in one of the small containers.
Another small container holds all the really nice actual clothing you used to be able to pick up in dressers/wardrobes/and crates (but can't get anymore since they added the Justice System a few years ago). They all became items you could steal and fence then; but they cut way back on their drop rate now so you can barely find them anymore, even when stealing from owned dressers and wardrobes).
Another small container holds a godawful number of lockpicks, soul gems, and empty soul gems; and all those little notes and stuff you amass from quests.
Two of the large containers hold all the extraneous and unwanted Crown Store furnishings that come with the houses and can't be sold because they are bound items = rocks; some of the trees; crates; barrels; etc. - all the junk or junky looking furnishings (like the scratched up Khajiit end table; etc.)
(that is all the crates I have, I think...)
