I have my ripple afghan going strong. I'm using Susan B's pattern and am enjoying it very much. The yarn is RH Super Saver, many different colors. I'm just sort of throwing in colors as I go with no set pattern of stripes. It's so much fun to watch this unfold. Love seeing everyone else's ripples. There is more on the horizon, especially a round one. I just love the looks of a round ripple.
I also have Jan Eaton's 200 Ripple Stitch patterns book and am eager to do several in there, both knit and crochet. So many ripples, so little time.
