Bags and more bags .

One of the items that will be quite popular for any Tailor is a bag. At the lower levels you may not be able to get huge amounts of money for them (depending on your server), but eventually you should be able to make good money selling bags. This will probably be at 340 skill, when you can make the Imbued Netherweave Bag. Most players at some point will upgrade all their bags to Imbued Netherweave or the even larger Primal Mooncloth Bag.

Specialty Bags
Tailors also have a number of recipes for specialty bags. The types of bags you can make include soul shard bags for Warlocks, herb bags for Herbalists and enchanting bags for Enchanters. These bags tend to sell for more money than comparable regular bags, mostly due to their unique nature and the rare components required to make them. But it would probably be a good idea to seek out these recipes because if you can collect the components you should be able to make even better money selling these bags.
