I'm not sure if their quilt retreat is open to everyone, though. They do have their retreat at the Cedar Lakes Conference Center, in Ripley, WV every year. I think their next one is in November.
I know of one that's open to 50 guests that's being held at Blackwater Falls State Park, in Davis, WV from April 26-28. Contact me if you are interested in that one!
