I am a member of Carol Doak's Yahoo group. I don't remember seeing any wedding ring patterns on her website, though. The wedding ring pp pattern is a somewhat challenging pattern (in my opinion). I've been pp for 15+ years and I haven't attempted one yet! Call me a coward.
www.quilterscache.com is a good place to try to find the pattern. Good luck. Post pictures when you can.
