I don't use batiks even though I have some but the fourth one from the left doesn't look like it belongs with the rest (the dots that make shape that is blue). But, like I said, I don't work with them yet. And I always make things that match. So maybe I'm not one to give advice. But all the others really pop!!! That looks like a hard pattern. Good for you!!! Are you taking the class online by any chance???
