I make and sell a few kinds of art. I used to have a shop on Etsy, but I've pretty much shut it down. To be successful in there requires an extraordinary amount of energy and persistence that I just don't have. The market is supersaturated, and it's hard to get noticed.
I started selling on Facebook instead through a group, and that's been very good to me. The bonus is you can make friends with your customer base and don't have to pay fees to list items. Etsy fees are not a lot, but they add up annoyingly quickly. Especially when you're struggling to sell.
Any kind of business is going to take a lot of marketing, though. Just be aware of that. Success is not usually a quick thing. But if you have the motivation, I say definitely go for it. The whole endeavor could even give you a reason to stick around. Art in itself is very therapeutic.
