I'm so glad someone started this thread! After making a giant star shaped afghan, I moved to the 12-point round ripple. I have done two now--one in pink and white stripes; one in blue and white stripes for a friend who is having twins--a boy and a girl in May 2007. I love them. It's great mindless crocheting once you get it started.
I can't post pictures right now--sorry! But I highly endorse this pattern
and will continue to make them over and over, I'm sure.
