http://find.mapmuse.com/interest/quilting-shops is a site someone posted sometime ago. I bookmarked it but haven't checked it out! Good luck!

After several years of not wanting to spend the money on the Quilter's Travel Companion book, I finally broke down and purchased one. For me, it was well worth the money spent.

My other source is this Board - always a great source!

Keep in mind that the Quilter's Travel Companion IS current when it goes to press. Lots of shops can close in the time between their deadlines and actual printing to distribution.

It's still a source I turn to coupled with hours googling everything I can. I also use the ads in quilt mags and sometimes those help me discover new places too.
