In tailoring, a player crafts many different things using cloth. Such things include bolts of that specific cloth, which takes a bundle of a type of cloth and compacts it into one bolt, spell thread that can be applied to a pair of leggings to improve spell power and stamina, and pieces of armor, which increase in quality as the profession skill is upgraded. The material that a tailor primarily needs is cloth. There is a wide variety of cloth to be found in the World of Warcraft. Cloth is obtained by killing many varieties of enemy npc's (non-player characters). The type of cloth depends on the level of the character’s foe. Such classes that benefit from this profession include: Mage, Warlock, Priest. These classes are only able to wear cloth armor, whereas all other classes can wear leather or better. Linen, Wool, Silk, Mageweave and Runecloth are all acquired in Azeroth, which consists of the Eastern Plaguelands and Kalimdor. Netherweave cloth can be acquired from the Outlands, released in The Burning Crusade expansion set. With the newly added continent of Northrend, released in the expansion set Wrath of the Lich King, players acquire Frostweave, which is used to level the tailoring profession from 375 to 450. Players become able to fly in Northrend when they reach level 77, and are able to craft the newly added flying mount for tailors: Magnificent Flying Carpet. This mount can be crafted after a player skills up their tailoring to 425.
Tailoring is a skill that turns cloth (linen, wool, silk) acquired from drops or from the AH (Auction House) into cloth armor, usually only useful for classes that cannot wear any armor better than cloth. This way, you can constantly improve your armor without having to wait for a good drop/reward. This goes hand in hand with enchanting or leatherworking. Leatherworking because some of the recipes call for leather, and enchanting because some of the armor you can make with tailoring is green or of a higher status than white, and can be disenchanted (no, disenchanting is not a separate skill, instead a enchanter disenchants things, gets their magic components and uses those to enchant other things).
What you make[edit]
You can make cloth armor, bags, and bolts of cloth, which are needed by other professions to make certain objects. You cannot make weapons since this skill is for working cloth. Cloth armor really only sells to vendors or for you to wear in the beginning. Eventually you can sell the high green, blue, and purple stuff you make in the auction house for a huge profit. You can wear the armor you make yourself, which makes it useful to have a tailoring level until you can make stuff that require your level or higher to wear (other wise you will never wear the stuff you make because you already have better stuff) Everyone loves extra bag space, and tailors are the only ones who can make them, of course you can buy them for more at the AH or even from a vendor. It is better for your wallet to make you own bags. The most basic recipes only require the bolts you make from the cloth, and thread (which you buy from a vendor). The medium level recipes can call for things such as leather or spider silk (from drops from spiders obviously), and always call for more cloth/thread. The highest tailoring recipes call for a huge variety of material that you'll either have to run all over the world or spend a fortune in the AH. However, the same holds true for all professions.
