Thank you! I used leather paint. I can't remember the brand, but it's kind of like a watered down acrylic. You don't need to prep the leather in any sort of way, you can paint straight on it. I would say sealing it with a resolene or lacquer would be helpful, but over time paint will come off anyhow. On this project, I opted for Tan-Kote so it could still be oiled.
