I've only listed places where I've found the drop rate to be better than 1 in 5 (20%+)

I have started adding co-ordinates for those of you that have a location addon.
Also adding the average levels of the listed mobs.

Feel free to add any good locations you know of, that I've missed.

N.B. where I've listed for example "Razormane mobs" that means any of the monsters within this family i.e. Razormane Quilboars, Razormane Geomancers, Razormane Defenders etc.

Also, Blizzard say that cloth only drops from "Humanoids". Now Humanoid by defintion, is something that walks upright on two legs. But not according to Blizzard. Centuars run around on four legs but are classed as Humanoid and Satyr's, whilst walking upright on two legs, are classed as "Demons" but still drop cloth, as do Undeads. Confused?
Thanks for putting me straight guys

The Stockades
Probably the best place in the game to farm wool. As a Horde, you’ll die a couple of times getting here, but it’s worth it, if your after lots of wool. It’s a boring instance, but the mobs have a good respawn rate. So by the time you’ve cleared the instance all the mobs except the bosses will have respawned and you can just start clearing it again straight away. Recommend that you be level 50+ to make life easier and faster, otherwise it won’t be worth the time. A clear run generally nets me about 60-80 wool and it takes me about 20-30mins to clear.
