Are there any leatherworking items needed to complete recipes for other professions?
For example, leatherworkers need iron buckles to make most belts and I'm always buying them through AH. There are also several items that require luck potions or potions of swiftness etc. that I'm assuming comes from alchemists. Bolts of linen/wool/silk as well.
These items are always in short supply and I'm wondering if there's a leatherworking equivalent. Armor patches perhaps?
