Ha, nice! You may be surprised, sometimes small stuff like that does way better in terms of margins and volume. Knew a guy who made custom metal furniture, and also made cheap little metal cross wall hangings and those sold like crazy while he was waiting for the furniture to move.
So what's a set of those go for?
Idk, but I would feel comfortable letting something like this go for $15... My wife (who is a badass artist) started to show me some of her ideas yesterday. Well, she of course, puts me to shame, but the sky is the limit to what kind of little designs we can make.
