It's dosnt have to be something useful e.g weapons, but what do u like to collect? I like the lexicons and them red glowy things in the steam robots lol

Forsworn headdresses. Take scalps and get a new hairstyle.

The only things i really go for and collect, is the bugs in the jar's and place them side by side on a shelf all the rest just comes by itself on the go.

Journals, I mean I keep just about every book I find, but journals actually get displayed.

Yeah that sounds pretty good, iv never try that

Lockpicks, every one of my characters have 100+ lockpicks at any time, I can't resist picking them up, I also love picking locks; if I can pick a master lock or open it by key, I'll just pick it for fun.

Septim.

ALL THE BOOKS IN THE GAME! JOURNALS ; BOOKS ; NOTES ALL OF IT!

Coin

Flowers, food, and books. I like dropping flowers around the houses, along with books, for one of my mage/alchemist characters. I like to call it 'structured-slob chic'. And I can't count how many times I've dropped decent loot in favor of loading myself down with alchemical ingredients and books. Also food. Lots of food. Enough to live off of while traveling anyway. And I might as well admit that I carry around clothes too. It's not right to visit a Jarl wearing bloodstained armor or mage robes.

My housecarls do not appreciate such refined taste.

(Is it possible to be a hoarder if you're carrying most of the junk on your person?)
