Leatherworkers seeking to obtain one of the Darkmoon Faire's top prizes (such as the amulet of the dark moon) can pursue this repeatable quest as the easiest way to fulfill their ticket requirements. 8 Rugged Armor Kits come to 40 rugged leathers for 20 tickets, which can be easily skinned by killing wolves and bears in Felwood. A fast grinder moving quickly from target to target will have no trouble getting all the leather he needs.

Once you're done, you probably won't want to see a skinning knife for a few weeks, I suspect; I had a bit of leatherworking burnout once my rogue got her amulet.
