Take time out to go to Navy Pier on the lake! I love it there. Just a good time to relax, watch the water, and the people. I don't know of any quilting shops there though, sorry.
We will be in that area over Labor Day for a family reunion, and have been to Chicago several times as my DH has family there. But I've not been to any quilt shops there.
I'll be watching here so I can see what is there too.
