I take pride in my leather work, and I feel it shows; quality should never be compromised. Anyone who says that quality doesn't matter would also have you believe that the earth does not keep secrets!
In my latest pursuit of high-quality materials, I have discovered thick yeti hides. Yetis are native to Feralas, often found west of here in Feral Scar Vale. I'll give you a choice of one of my leather goods for a stack of ten. If that is agreeable to you, then we are set!
Ah, excellent! These hides, when given a special treatment, are as resilient as iron I tell you! It will take many tries in order to get the right mix down for the tanning, but I am confident they will bring my mark of quality to the next level.
As for you, <name>... your assistance has proven invaluable to me. Please take your choice from these items I have crafted.
