I really need to organize my bags

I made a comment the other day while in-game that my bags were too full and needed more room. The person I was talking to asked what was in them ... and that's a great question. At the time of that conversation, I took a screenshot:

Let's go over them bag by bag!

1. Originally this was meant to just house consumables. You can see a number of potions and some food in there, but the bottom row also has 3 reputation tokens for factions I've already reached exalted with. They're bind on account, so I shipped them off to my banker alt. There are two motes in there that I got while farming for MoP factions that ... I'm not really sure what I'm doing with them. I should probably just sell them in the AH. There are also a couple things in there related to world PvP (they don't work in BGs or Arenas) that I will never use and should just destroy (I had been holding onto them so when I looted them from my War Mill they didn't end up in a random spot).

2. All my follower upgrades that I've saved. The bottom two rows are the lower level - 9, 6, 3 - and the top two rows are the highest level - 45, 30, 15. Most of my followers at 675, and while there are some that could be leveled up, I am mostly just waiting to do so until it's actually necessary.

3. The top of this bag is meant to be overflow. You can see a variety of items here: the 20 stack of crates are from the Salvage Yard and I just need to go through and open them; there are a couple of PvP pieces from past seasons that I picked up with honor for Transmogs (they need to go into Void Storage); there's a bunch of vendor trash from mining; there are some of the daily pet reward tokens (the blue medal looking things); there is a stack of broken bones from Ashran; and a stack of 27 crates for the Barn.

4. This is my professions bag. At the time I had a crazy amount (for me, at least) of Primal Spirits from handing in excess ore to the ore trader.

5. Extra gear should go here. I have a number of PvE pieces as well as a secondary set of PvP gear for my off-spec (resto).

6. Originally the bottom of this bag just had a line of consumables to use on the Timeless Isle (farming rep for a Heavenly Golden Cloud Serpent). Since then, I've just started dumping stuff from Follower quests into there as well (some specific Follower Trait rerolls, some Halaa tokens, some Steamwheedle rep items).

7. This has a number of PvP items in the top of this bag as well as my normal hearthstone. The PvP items are: a gnome heart that lets you see Gnomes near you (killing 500 gives the title of Gnomebane), an item that allows you to collect Bloody Coins while on Timeless Isle, and an item that allows you to collect Bloody Coins in regular BGs. There are some more specific Follower Trait rerolls up here, too.

It's kind of sad that I have the largest bags possible and still no room. I definitely need to just organize better.
