Oh I love Prague!!! Waiting for the time I can go back again. When I was there I did not see a fabric shop, but I didn't look very hard either..... so much to look at!! But I did find a shop with hand done embroidery of which I had to purchase a few things. Even tho I was taught to do these myself, it was so special to get something from there. I also spotted a lady crocheting in a park and bought a few things from her. Anyway, keep your eyes opened to all possibilities....you will have a fabulous adventure!! Show us all your goodies when you get back!!
