I like the smell of leather, and I know we use it in so many goods, shoes, jackets, belts, furniture, etc. It's so useful!
I have always liked that snell too!
Yes, leather can be made to satisfy so many different styles and preferences, so versatile. 
How long of a process is it to make it?
There are different tanning procedures, which can vary in how long it takes to cure the leather. Many times it is vegetable-tanned, and often oiled to improve resistance to water.
Where is this done at?
A tannery is the location where skins are treated and processed into leather.
Are they more common in some states than others?
