Below is a great resource intended to help you level Blacksmithing from 1-375. It is best that you use this in conjuction with Mining and mine as many of your materials as possible (Ore & Stone, mainly) This will save you a lot of money on the Auction House, give you a second level 375 skill and provide you with the means to make more money later (check out our Mining Guide for more information on mining.) However, you can certainly follow this guide without mining.
