The Quilt Minnesota Shop Hop is August 1st through August 17th. There are 8 shops listed for the metro section. On the Metro page the website links for each shop are listed and also the hours they are open. There is also a map that can be downloaded, showing the location of the shops. The site is easy to use. Just click on another section to see the information on the participating shops and get a map of the area.
You didn't mention when you will be visiting here, but if it's not during the shop hop, just check the websites for the shop's hours. I went on the Metro bus tour last year and thoroughly enjoyed it.
