What item can I farm that sells fast?

[myjudgmentx]

I'm on a heavily populated realm, and have farmed savage leather + embersilk. However it's taking a long time to sell what I found in 2 hours. It's even the cheapest on the ah. What item could I farm full bags of, and expect for it all to sell in 1-2 days?

do some research on you realm what sells good, verry simple

This a tiny bit of research is worth hours of farming, no one can tell you what is good gold on your server without knowing what server you are on and DON'T TELL US YOUR REALM.
I recommend using some of the excellent guides on the internet which give you a good idea of what can make gold, then you just got to check prices and demand and start farming.
