where do i find netch leather in skyrim
It's an item specific to Solstheim. Like Michael said, you can kill the big floating Netches. They're relatively slow, but hit hard if they get close. Arrows from range aught to do the trick if you've got a decent Archery score or relative magical ability. You can also buy them from the merchants on Raven Rock. Other than that, random loot is the only way to get it, but Netch Leather won't appear in Skyrim proper, it's only going to appear on Solstheim.
