I am working on a batik quilt too in blues and greens with the Gimme Diamond Pattern. My quilting expertise is not at your level, as my hand quilting is only in the ditch. I still have to finish the edge. Might try the squares, you show on the border. Time will tell. Hope to be posting by next month. question, I have never worked with batiks before, I did prewash. Do you think the batiks will run, I sure hope not. Love the colors you choose.
