Hi! I lived in eastern Michigan for 30 years and western Michigan for 30 years before moving to Minnesota a few years ago. I had to do LOTS of asking and searching to find quilt shops and shows in this area.
I googled "Michigan quilt show 2011" and had many hits. Here are a few:

http://miquiltresources.blogspot.com...ilt-shows.html
http://cameoquilters.org/-.html
http://www.wrbqinc.com/events-mi.php
Try googling the above and add a city name. ex. "Michigan quilt show 2011 Port Huron"
Hope this helps! Have fun searching!
