It looks like Aboriginal Australian dot painting, an art form that I really love. Can I please stress if you’re looking for something like this there are thousands of talented Aboriginal artists across Australia who make fabrics and other artwork like this that is not only truly authentic, but helps them to continue practicing culture that was forcibly stolen from them by European colonisers. Cheap knockoffs by non-Aboriginal artists only serve to further devaluing the world’s oldest continuing living culture.
There are plenty of authentic Aboriginal artists that ship overseas! I’m sure you’d be able to find one with fabric that you like, however shipping may be a bit costly depending on where you’re based.
It’s actually a really common technique called pointillism. While this particular pattern may remind you of something aboriginal, it is just a neat landscape inspired pattern using pointillism. So sharply labeling something as aboriginal and then strongly demanding everyone order from Australia is a bit over the top. I’m not saying it doesn’t draw inspiration but if we had to support every source of inspiration for all the patterns and designs we use, it would be madness.
