I sewed with LEATHER for the first time and it wasn’t that hard! Even six years later, I’m still impressed by what my Bernina 740 can do. I just put in a leather needle, selected the “leather” setting, and went to town. 
I used the Noodlehead “Petal Pouch” pattern I already owned (the small size is great for holding knitting notions) and a soft leather scrap from my trip to the creative re-use store. For the lining, I had the perfect size Liberty scrap leftover from a 2017 shirt. Blammo! A luxe, shiny little pouch made from, essentially, garbage.
