Silk Cloth Farming
Silk Cloth is the third cloth you will stumble across in the game, Linen and Wool coming before it. As with all other cloth it is used primarily in Tailoring and First Aid. Silk is actually a fairly common drop from mobs in their late 30s but since players level through this bracket so fast and so much Silk is required for professions such as Tailoring it is generally overpriced on the Auction House. On average I see stacks of silk for 15-17g but sometimes it can sky rocket in price up to 22-45g a stack.
The good news is there are roughly double the amount of areas to farm Silk Cloth that there is for farming Wool. Also a lot of the later levels double as farming locations for Mageweave Cloth too. As with all other cloth farming locations though, it is always better (if you're a higher level) to farm instances. So, as always here is a quick list of all the good instances for farming Silk Cloth.

Well, that about does it for good instances to farm Silk Cloth in. There are other instances that Silk will drop in, of course but they aren't as good as the above instances when it comes to farming Silk. As for locations for lower level players to farm Silk Cloth, below is a list of every good location that I have found.
