Hey, just tossing this out there since I seem to be running in to a fair number of people who don't realize this. When you start the materials-provided levequests you get enough materials for 2 extra attempts.
If you succeed on every crafting attempt, you can still use those two free attempts for extra skill and xp.
I.E. if quest asks for 2 hats, gives you mats for 4, you can make all 4, get xp and skill for all 4 and, though it does take all 4 during the quest turn in, the mats were free anyways.
