I don't care much for groups and MWK is the only group I belong to now, but today I joined The Sweater Workshop Yahoo group. For those of you who are working from this book, you might want to join. Jackie Fee is the moderator and offers advice and assistance.
I might add that I've had a couple of very pleasant emails with Ms. Fee and she is great!
So, if circular seamless knitting is for you, come right along and join up!
