What are ways to independently make a few bucks on the side?

So I was just brainstorming a bit thinking of ways to earn a little extra without the responsibilities of actual employment, meaning you can do it when there's time and put it on hold if you have to. Personally I like crafting so I could imagine having something like a little etsy store. I could carve beads from wood, antler or bone and turn them into jewelry. Something like that. That wouldn't just be a way to make money but also sounds like a nice hobby. Not sure how financially feasible it would be though, maybe someone here already has some experience? But yeah I'd love to hear about your ideas/advice. Anything that's legal and not exploitative, be it entirely independent or also freelancing stuff that doesn't require special training.
