The Gems of the Prairie quilt guild from Peoria, IL, is having a quilt show, Autumn Gems, on Sept. 24-25 in Pekin, IL. You'll find a link to the flyer at this site:

I've not been to this show for a few years but have gone before and it was very nice. The flyer says there will be 500+ quilts, a bed turning, classes & demos and more!
