- To purchase the recipe to make these gloves, fly to Astranaar, goto Benjari Edune, (18,50) and pick up the quest Three Friends of the Forest.
- Complete the quest by finding Bolyun (18,60) and accept his quest In a Bind, kill Kaliva when she spawns behind you and loot Heart of Kaliva.
- Complete In a Bind by handing this in to Bolyun and then you will be able to speak to Harlown Darkweave and purchase your Pattern: Herbalist's Gloves.
I haven't tried selling the actual pair of gloves as I do not have a leatherworker ( nor a LW friend ) but I can imagine if you slapped gatherer on a pair of gloves you'd be able to easily sell it for 2-300g per pair. Time is precious to others a +10 herbalism boost and +5 mining boost is priceless when you're leveling gathering professions.
That's all folks,be sure to craft that gatherer and list them at the Auction house. Also be sure to snag some herbalist's glove pattern and sell them at the Ah for easy profits!
