There is a quilt shop in Munich called "Quilt und Textilkunst". The adress is Sebastiansplatz 4. You can look at their homepage www.quiltundtextilkunst.de (in German). The shop is open monday to friday 8.00 a.m. to 6 p.m. and on saturday 10.00 a.m. to 2.00 p.m.
I have never been there but a friend told me it is a great shop!
Have a wonderful trip to all that wonderful towns!
