I suggest 3 things - check with your city's Parks and Rec dept. Most have classes and stopping by a class to talk with the instructor should give you leads. Stop by your local quilt shop and ask (you can try the big fabric shops, but we don't often know about the clubs/groups). Google quilt guilds and it should show things within about a 20 mile area. As a side, your local quilt shop may have some additional people who have been wanting to start a group - so you may be the catalyst for a whole new group!
