Alright well, most low level items you get from Skinning, Mining, Fishing and Herbalism (tell me if I missed one please) sell for a lot more than they should (thats my opinion), for instance: light leather/medium leather, and sell it in the AH. It sells for a lot considering the fact that its EASY to get. I make 100-130G a day on a level 25 if I work VERY hard. And you can go farm low level cloth also. Linen sells for a ton on my server (75s-1g20s a stack) and so does Wool (1g-2g30s). And some advice is to not get "production" skills until your level cap or close to it. The reason is you will make much more gold just with gathering skills because you don't use them to make something then sells for 10s-3g more than it took to make. (10s at very low levels mostly and 3g for higher levels) For instance using your 18 Thick Leather, 2 Thick Wolfhide, 8 Wicked Claws, 4 Heavy Silken Thread and 2 Cured Thick Hide you make Wolfshead Helm (Thottbot World of Warcraft: Wolfshead Helm) which costs around 28g to make on average. Then you go to sell it and find out it sells for 10-13g! (based off thottbot) You could have just sold 18 Thick Leather, 2 Thick Wolfhide, 8 Wicked Claws, and 2 Cured Thick Hide and made 27 gold! Thanks for reading everyone and hope it helps. And please don't flame me about saying this is useless for high levels because right now I'm saying it is for low levels to medium levels. I think the reason that this works is people get to 70 and don't focus on professions so they need to learn one, but to get their skill up fast they just go buy the low level mats at the auction house.
