How do you do this? I mean, the people I know well to invite probably wouldn't have anything to swap that would fit me or I'd be interested in. Others that I don't know as well might think I'm off my rocker....how do you do this & have it be a success? Thoughts, suggestions? Anyone else in the midwest? Do you guys ever do one of these here? The Seattle one looks like it was so much fun & such a success. I would love to do something similar!
