Going to Germany?
Then you may want to check out the Kiosk Book on Germany. The folks at Kiosk which is a site/shop that I love have put together 120 pages of resources for fellow travelers.
In case you're not familiar with Kiosk: Every few months, they launch a new collection that is based on their finds in a specific country. First there was Japan, then Sweden, then Mexico, and now Germany. (I think Finland is next!) More books will follow, which is great because I'm always struggling to find a good, comprehensive guide to the cities that I visit. I usually end up putting together info that I gather from magazines, guidebooks, the Internet, friends, etc.
If I ever open up a boutique, I may have to borrow from Kiosk's model. What an awesome excuse to travel AND shop! Oh, and then write a little book, too? Those are almost all of my favorite hobbies combined!
