Leves are the best way to level your crafting classes. They are more time consuming the Collectables, but offer huge experience rewards for their completion and are viable at all levels. Just remember that you can only do a total of 100 before running out of tokens to do them with. 6 Tokens recharge per day (3 tokens every 12 hours).
Also consider simply purchasing the items you need for Leves from the Market Board - and always check the NPCs' prices first! Some players make a fortune by price gouging common Leve materials and items that can be easily purchased from NPCs on the cheap.
While not the best way to level crafting classes, collectable turn-ins offer an alternate approach to leveling. These can be expesive and difficult for the amount of EXP gained and it not really recommended.
Grand Company Turn-Ins
Your Grand Company has a list of crafted items that they will want. This list refreshes daily and can be used to earn very high amounts of experience, usually about 10-20% of your total exp needed at that level! Turning in HQ items will yield even more EXP.
