I posted an invite a couple of years ago, suggesting about an area about 30 or 40 miles around where I live. I have access to a great quilting room. Our first meeting was at a quilt shop which had just moved, about 25 miles from where I live. The day went wonderfully. A few of us meet once a month at my place because I have a great quilting area.
Perhaps starting off with a meeting at a quilt shop was the clincher for us. We got to see each other before committing to anything. Now, I've got to get going and meet a couple of them at a quilt show near where they live.
