How I intend to make my money

Leatherworking will be my primary source of income.

Currently I try to buy Borean Leather under 14g a stack and turn 6 stacks into 1 stack of Heavy Borean Leather.

Once you get into the Heavy Borean Leather you have lots of options.

Heavy Borean Leather

Put these up in stacks of 1, 5, 10, 20.

Arctic Fur

If you are paying 14g per stack of Borean Leather then moving these at 55g will net you about 10g. Tend to be in high demand so keep them up.

Heavy Borean Armor Kit

I tend to be able to move several of these a day at 25-30g each. Which nets about 7-12g per.

Icescale Leg Armor & Frosthide Leg Armor

Be sure to keep a supply of Frozen Orbs so you can keep making these things. Also make sure you have several in the AH on raid nights. Its hard to not make a profit with these things.

Mammoth Mining Bag & Trapper's Traveling Pack

These tend to be my highest profit per item going anywhere from 90-150g while only costing about 35g.

People have also had success with the LW rare PvP sets. I haven't tried these yet but I can see potentially profit with some of the  Stormhide and Overcast set pieces do to there relatively low cos 35-55g. I'll try crafting a few and see what I kind of success I have.
