Wow, that sounds like a very interesting itinerary. Do keep us posted.
I am in Vienna now, heading to Croatia shortly to give a talk at a meeting including some of my new friends in the Eastern Euro textile industry (only tangentially related to what I do). Some were pretty high up in the Soviet era fashion industry, especially Hungary, and told me there was a respected and thriving industry, but USSR demands put quantity well over quality. It will be interesting to see what you find now.
PS: Sample the borscht (and other culinary offerings) and report back, too, please.
