Here are some common questions dealing with real-fur masks.

Isn't it heavy?
That depends on the type of leather. Rabbit leather is very light and can often be lighter than faux fur. Goat leather is a bit heavier, but still light. It has a comparable weight to that of thick faux shag, sometimes slightly heavier depending on how much is used. Deer leather is thicker, and cow leather is quite thick. Using these thick leathers for large masks can weigh you down.

Won't your sweat or breath cause the leather to dry rot?
Any leather needs to be kept away from moisture. As for breath, none of your breath inside the masks I make will come in contact with the leather, as the nasal passages do not contain leather, and neither do the nostrils. If you are a sweater, I'd recommend wearing some type of ski mask inside as to protect the leather around the back of your neck. (That is the only area that can come in direct contact with your skin)

Isn't it hot?
Leather does not allow heat to escape, which requires additional ventilation areas in all-leather masks. This will help you breathe well and keep a good temperature. On a side note, I don't recommend these masks to be worn in scorching heat. That should be the case with any full overhead mask, with exceptions; though especially so with leathered masks.

Doesn't it smell?
If you don't like the smell of leather, you shouldn't buy a leather mask. If a pelt is tanned incorrectly and smells bad, I'm certainly not going to use it for crafts. Stinky pelts=trash. Then again, there are some species with a natural barn smell, that can be difficult to remove. Rest assured, I won't use any such pelts with an unpleasant odor.

Why use Real over Faux fur?
Personal preference, that's all. I enjoy the challenge of working with real fur, and the end result is often not comparable to that of faux fur. It commonly has a more realistic appearance, and can be way softer. There's just something about being able to say; "I'm wearing what an animal once wore."  That may be odd to you, but each to their own. I do also use faux fur at times, because it is usually cheaper.
