I have no idea how it works, but if you sold/licensed/created your art to fabric patterns, theres almost certainly a small market there. Clicking through your site (others are right, you could present your work better), I see plenty of “I’d buy a decently priced cool shirt of that pattern”. Sample size of one and all.

You’re much better off selling shirts. The markup on custom printed fabrics isn’t great, and there are plenty of professional fabric pattern designers out there which companies that commission fabric hire as-needed.

Honestly though, unless you’re pretty much only selling in person or too small to notice, someone is probably just going to rip you off using AI and sell shitty knockoffs on Etsy
