Things discovered while cleaning my closet:

-$5 in change
-A rubber bat
-My Little Pony magnets
-A long ponytail of my own hair
-4 pairs of shoes that fit
-4 pairs of dress shoes that fit but I wouldn't want to wear for long
-1 pair of Converse sneakers that do not fit
-A collected volume of Storm Constantine's Wraeththu trilogy
-One deck of Fushigi Yuugi playing cards
-5 duotangs full of my fanfiction
-2 GLAY CDs
-Miscellaneous unlabelled burned CDs that I'm going to have to check out later
-The warranty for a computer I bought in 2008
-A roadmap of Scotland (bonus: I have never been to Scotland and do not intend to go in the future)
-A very large Norwegian flag
-Two boxes of Prismacolour pencils

...And much, much more.

Keep in mind that I "cleaned this up" earlier this year. /cough

Oh boy. Some of this is going in the bin, some of this is getting recycled (I keep the handwritten drafts of my recent fics, but I really don't need the ones from 2009, do I?) and some is going to the secondhand. ...But I'm probably going to keep more things than I really need for the time being. I don't need eight pairs of shoes, but I have a thing I need to go to in August, want to keep my options open, pfff.

...I am definitely going to re-read Wraeththu. I don't know if I would like it now, and I'm really curious! When I was a teenager, it hit my id so fucking hard, man.

Also: I've mentioned before, but I'll mention again, Marie Kondo's suggestion of storing one or two bags/purses inside the other is great. It helps them keep their shape, and it frees up a bit more space. I have a few messenger bags in there, and man, it really helps to store them nested like that.
