Remember that you can make more characters as mules to hold your stuff. Personally, I'm working all tradeskills except for blacksmithing atm. You can get provisioning and alchemy done fairly quickly. Then you just need to keep whatever you need to make the food/potions you want. Can get rid of the rest. Getting rid of my low lvl provisioning stuff made a ton of space. You can deconstruct stuff from tradeskills you're not working or you can sell it. My tip would be to not work one of the skills at least so you have stuff to sell to make some gold at first....gets you more bag slots, etc.

Decon everything.
Sell provisioning and alchemy, unless I can use them at that moment.
Get rid of all the racial mats.

Stockpile everything else.

Sell the junk. :P

I have 8 characters. One toon is my provisioning mule, another is my enchanting mule. I decon everything I get. I play about 30 minutes a night and spend 2 hours a night dealing with all the stuff I got while playing.

If I have no free research slots and find a new trait, I'll give it to an alt and have them research it. When my main crafter is ready to learn another trait, I'll have my alt craft it up for them. Saves bag space while retaining traits, at least for a little while.

I made the decision early on to split up the crafts with my SO. He handles the smithing professions (Woodworking, Blacksmithing, Clothing). I handle the consumables (Provisioning, Enchanting, Alchemy). My bank is primarily crafting mats only with a full stack dedicated to each of the mats I have decided to keep (not all of the mats mind you as they are not all necessary for my needs). Any runoff of common mats (Ta for example) get donated to a guild bank or sold to players.

We share drops so I give all of my dropped gear to my SO to decon save for set pieces which I either deposit in a guild bank or sell to a player.

My bank also has a few hand-me-down set pieces currently that I'm passing along to an alt.

The only things I sell to NPC vendors are green recipes (so common there's no point in trying to pass them off to players) and vendor trash (Foul Hides, Elemental Essence, etc.). For all other items, I either decon or pass along to the SO for decon depending on craft, sell to other players, or don't pick up in the first place.

I have a few bag alts for deconstruct, enchanting, trophies\unique, and one for blacksmithing/clothing/provisioning. 90 bank spaces, 80 on main toons, 70 on alts.

I carry all my alchemy ingredients on one of the characters I play. Don't know why really but I do play him as more of pure quester rather than horder.

Another toon I play runs around killing & collecting everything without a care in the world. I try leave a lot of open space on him before going out.

I keep items/materials I am currently trying to find or find more of on my characters and in my bank. Materials I have enough of go into storage and I don't waste time or space collecting those items again until I start to run out.

The biggest challenge is logging in/out all the time to manage it. It's the one thing that really makes me start to lose interest when playing.

I have 3 characters, each a different class and in a different alliance, each of which levels 2 crafting professions, preferably related to their class. This way all quest rewards, loot , etc are swapped between characters and sent to the one who needs them most. I keep in bank all the generic crafting mats. Each characters holds on only to green/blue gear they haven't researched yet, which they will use until its durability drops. Then, the equipment is destroyed for research, and they equip another piece they haven't researched yet. Everything else gets deconstructed.

I keep any item I need for research. I keep any crafting mats (including the mass of provisioning mats) that my be useful to clothe/feed any of my alts.

The inventory system is really harsh on anyone who hasn't yet fully decided who is going to concentrate on which skill, or whether you might need those level 5 ingredients in case you start a new character. I am sure it works well for those who start 1 character and play it through, but for the rest of us it's a bit 'meh'.

I used to deconstruct all of the armor and weapons I got but wasn't going to use, but now that those tradeskills are somewhat leveled and I always seem to be strapped for gold, I've started selling off the white quality armor and weapons that don't have traits on them. If they have traits, I usually try and put them in my gbanks so that others can use them for research.

On my main character, I keep one food item stack, one or two potions depending on what they are, any foraging stack that is under 10 and unable to refine like wood, cloth, leather, ore, etc, Soul Shards, and lockpicks.

What I keep on one of my alts are all the cloth and leather stacks I've gathered while leveling that I have no use for and either intend to use for guildmates or try and sell in the guild stores.

Another toon holds items for me that I cannot use yet but will at some point during my game play, such as Daedra Hearts, higher level cloth, tomatoes (lol), etc.

I HAD been keeping Alchemy Reagents in my bank too, all of them, but I just don't have the space. Now, with the exception of the four kinds I wish to keep for potion making, I send them to another alt as well.

Finally, in my bank I have Weapon and Armor trait gems, motif style ingredients, one to two stacks of the material needed to make the armor/weapons needed for my main character's current level, provisioning ingredients that are materials for the purple quality recipes I can make, all of the tannin items that are used to improve armor and weapons quality, and anything I need to transfer from one toon to another for storage.

LASTLY, I keep all of my extra motifs I've found plus any item I'm saving for research in my MAIL. I send it to my boyfriend who has the Wykkyd Mailbox addon which auto-returns it to me if it's titled Bounce or Return.

I have two bank alts and is thinking about a number 3.
They store costumes and other cool stuff in addition spare siege equipment and parts of sets I collect.
Use the guild bank to store cheap stuff like racial style stones.
Don't generate huge stacks, you don't need 350 crafting materials, neither stuff who is below your level.
Once you reach 100 make stuff and switch for deconstruct, exception here is that you might want to keep more than 100 for your primarily armor material for crafting sets and perhaps experiment with various looks.

I'm with nudel here. My husband and I split the crafting professions. I have one alt that does wood and enchants, and another to handle light/med armor. He has 3 alts that handle blacksmithing, provisioning and alchemy.

We save pretty much EVERYTHING. He sends all of the runes, glyphs, light/med armor and wood he collects to me, and I send all of the metal stuff, food and plants I collect to him. We also have 1 or 2 additional alts we play that are sending things to our crafters.

I never worry about deconstructing something I may want to research later. If I don't have a research space open, I just decon it. With so many chars sending me stuff, the chances that I'll get another item with that trait are pretty high.

When I have excess mats, I look for folks wanting to buy in chat. Same for the hubby. If I can't sell them to a player, I'll go on a making spree to test styles and what not. I usually vendor those off for a little gold, since the XP gain for deconstructing something you've made is minimal.

I have some set pieces hanging out in my bank, waiting for the alts that can use them to get to the appropriate level, plus all of the style/trait stones, so that both my crafters have access to the full inventory. I also have a mule that carries mats I can't use quite yet, treasure maps , extra motifs, etc.

Which reminds me....it's time to do a little inventory maintenance ....
