if you’re looking to make it a hobby not a living go to your local tandy store (There’s probably one quite close). Talk to the staff, buy one of their starter tool kits like the delux or whatever, work through the projects. Most Tandy stores have classes on Saturdays you can attend, there’s usually a facilitator there that will help you along with your project, give advice etc. There’s a shit ton to learn.
If you want to learn to make one specific thing that can be quicker but you’ll generally still have to learn all the skills (cutting, bevelling, edging, sewing etc).
I’ve only ever made flip flops for footwear. I’d like to make myself a pair of boat shoes but most shoes require lasts and I haven’t got any, nor am I looking to spend a bunch on them . . .yet.
