There is a farmer's market in Holt, MI (near Lansing) that we might want to check out. The rates are reasonable and the best part is, they allow booth sharing! Please refer to the Yahoo group message I sent earlier today for more information.
Otherwise, here is a link to the Etsy forum post I heard about it on: http://www.etsy.com/forums_thread.php?thread_id=5603283&page=1
