Enjoy your travels and explore all of those magnificent places and please don't waste your time looking for fabric as I did. The fabric in Europe is much more expensive than in USA and the merchants are telling me that they get their fabrics from USA. An owner of a fabric store in Ohio confirmed this and stated that she regularly ships bolt of fabric to Prag and Budapest and some other places. Last week I checked some shops in Trieste, Italy and I was not able to find anything. I am staying in Croatia for a couple of months and I am glad I brought my fabric from home because trough my travels trough Europe I was only able to find one french fabric.
Enjoy your trip.
