Follow my steps:
First you find a old leather sofa that people has thrown away on the dump, then with a sharp knife you cut carefully the still good and usable leather of that sofa.
When you come back home dry the leather if necessary or clean it well and remove all old cracked paint with a sharp knife, I made once a half moon knife from an old table saw blade, but any metal thing that you can scrape with will do or even a steel brush.
Well now you have your own stock of leather to make your own nice creations.
