I just finished an Irish Chain with white in each 9P and white for the open square -- then I I hit my stash and made all the 9P's with different fabrics. I had to repeat quite a few, but my only "rule" was that I couldn't have the same fabric next to another piece of the same fabric. My quilt is bright and cheerful and doesn't "read" any one color. It's also a bit different from most Irish Chain quilts. Sorry I'm not equipped to include a photo.
