Would selling custom terrariums or botanical art be sustainable as a side gig?

Considering a side gig selling custom terrariums or botanical art

I’ve always loved working with plants, and lately I’ve been wondering if I could turn that into a small side business. I’m an animal trainer by day, so I’m used to patience and creating habitats, which feels like it could translate well to building little green worlds. I’m curious if anyone here has experience selling things like custom terrariums or pressed flower art. Is there a decent market for this, or is it pretty saturated? I’d be starting from scratch, so I’m trying to figure out if the time and material investment would be worth it in the long run. Any thoughts on where to begin or what pitfalls to watch out for would be super helpful.
