Just my $.02, but you can do leatherwork with no tooling, but the other skills, cutting, stitching and edging are critical. That's where I'd start. Lots of threads here to search with tips on burnishing edges, stitching, etc. youtube videos are also helpful. Try Nigel Armitage. He teaches how to cut, round corners, edge and burnish and his stitching videos are great. And by all means, post your progress! You can get lots of constructive feedback. We all started from zero and all of us are still learning. I know I am.
