I know its only a small passive income an artist could have on the side if they're lucky. So wanna ask a few questions, would that be worth having, and which site would be best for someone who's not gonna do any of the production/mailing myself lol.

I'm bad at doing research on these things. Especially cuz sites come and go, falling in and out of style/favor. Like, Etsy and redbubble are the only ones I know exist lol.
