Leatherworking/rugged leather

Hello, I have a lvl 19 priestess with her level frozen. I’ve been trying for months to get the white frost sabre from the Winterspring quest. I’ve killed thousands and thousands of creatures all over Azeroth and can’t get any rugged leather! I can’t buy it from a vendor or the auction,What is wrong ,what do I have to do? As I said I tried the Yeti’s in Winterspring,the Blasted lands, the volcano,Dragonkin etc! I recently switched from tailoring to leather working and that didn’t help! Anyone else having this problem? I’m so disgusted I don’t even feel like playing anymore!

Note the comment about needing to have skinning up around 280 skill level.

what kind of leather are you getting from winterspring and blasted lands? are you skinning them or are you expecting loot drops? Best bet is to have someone with a high skinning skill around 250-300 in vanilla skinning to do it for you and just pay them for their time.
