I don't talk about my zines (<a href="https://kradeelav.itch.io" rel="nofollow">https://kradeelav.itch.io</a>) and artwork to people IRL -- it occupies a very liminal space in my mind and soul where I can mention things a bit too raw or depraved for office spaces. ;)<p>While I don't make zines to make money, per se (going as far to give a free digital copy on my site), there's still evidentially enough people that buy them that it technically counts.
I built a system to help people take payments with Google Forms. It was very much an MVP but I lucked into a niche that hadn't been filled, so each week a few people found it and started to use it. I charged 2% of the transaction volume (later lowered to 1.5%) and made about $3k before shutting it down at the end of last year to focus on other things.<p>Interestingly by that point there were much better, cheaper alternatives and the friction of switching was low, but I had a hard time convincing people to stop using it.
My partner and I started roasting and selling coffee (<a href="https://tinywaffle.co" rel="nofollow">https://tinywaffle.co</a>). My day job matches donations 2:1 so I've been funneling in proceeds to max the $10k benefit. It's been fun learning about coffee, marketing, and design.
