Skinners ensure that nothing goes to waste by removing the hides of dead beasts and amassing piles of fur and leather. Skinning is a straightforward, convenient profession for those already engaged in hunting animals, but it's highly useful, too. Exotic leathers (such as dragonskin) can command high prices, and they are critical to leatherworking plans, as well as some of the recipes of other professions.
Skinners can easily remove a slain beast's hide by ensuring that they have a skinning knife in their inventory, then right-clicking on an animal's corpse. Though not all beasts can be skinned, the vast majority can - and you don't need to have killed an animal to skin it yourself.
As you skin more unusual and difficult creatures, your Skinning skill will improve. High skill values are required to successfully retrieve leather from high-level beasts.
As a gathering profession, Skinning is regularly paired with complementary crafting professions, particularly Leatherworking, though Tailoring also utilizes some leather.
Approach a slain beast (along with some dragonkin or insectoid foes) with a skinning knife in your inventory. You'll see your mouse pointer become a 'knife' icon when you're close enough to the beast to skin it.
Right-click on the corpse to skin it - then, you'll be able to loot hides and/or leather from the beast.
