The Rage Scar Yeti are in an open area just on the west side of the mountains, so you will want to take the trail back north (toward Desolace).
Additionally, in killing 6 yeti I received 4 Thick Yeti Hide as drops and 6 from skinning, so it could be that it's a 100% skinning rate for the quest item.

You will probably run out of Yeti to kill in the open area before you collect 10 hides. Be sure to head up the path on the east side of the clearing to a cave entrance at 53.1, 31.8 to find more Yeti to kill.
Yes, the Perfect Yeti Hide does still drop. However, I've found that it only drops from the Feral Scar Yetis that you must kill in the follow-up to this quest.

Description
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 north of here in Rage Scar Hold. 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!

Item facts are the current retail client’s (ItemSparse); the specialisations for a pick-one item are the ones the Blizzard quest API lists; faction and currency text is the client’s own. Lowest listed price = the US commodity auction house now.
