I am super bad...
I have a house that I call "home base".... this is where I keep all supplies relating to "everyday life" Regs, food, potions, bandages (some), bolts, arrows, scrolls, anything I might need for a character like Power Scrolls, Alacrity scrolls, transcendence scrolls, and such... I have about 8 accounts so each account has it's own chest and inside each chest is a bag labeled with each name of each character on that account.... This is where they keep their "personal" items...
Then the house has 4 chests I like to call... Drop boxes.... These are where I dump stuff whenever I've gone hunting, shopping, or to an IDOC... I try to clean these out once a week or so and put the stuff away.
Then I have a house dedicated to armor and jewelery.... this house is filled with all sorts of armor and jewels sorted into groups... all the leggings, hats, gorgets each have a box then those are sorted into things like Luck armor, LRC armor and "resist" armor... I have about 6 chests for "artifact" armor... and the jewelery is sorted by type, LRC, Mage, Skill, Luck, HCI DCI and DI are all in separate chests and each type is further divided into Rings/Bracelets...
I have a house I use just for weapons, Each category of weapon has 4 separate chests... Maces, Swords, Fencing, and Archery each have 4 chests, they would be heavy hitters, Slayers, Use best weapon skill, and Spell channeling. I also have chests for "artifacts" and Mini arties. As well I keep all my musical supplies there too...
I have a house just for plants.... where I sort them by color.... I have a house for deco stuff, and a house for Crafting... And then a place where I keep mostly just all the "gift" junk that I have. Valentines to X-mas...
It's bad and I always say if anyone ever saw all my crap they'd probably faint. I guess I'm what's considered a horder. I have trouble parting with things... I outfit I don't know how many newbs all the time... from weapons to armor... sometimes I even throw in the "bonus" arti... or mini arty... I can't help it I love helping people. I also do a bunch of designs for people and sometimes hire myself out as a decorator, which I truly enjoy. So I guess I don't like to part with anything because I'm always afraid that the moment I do I'll have a need for it.
