Oh my, you lucky girl. At the moment, I am sitting in a hotel room in Milan, Italy. The weather over the last two weeks has been absolutely spectacular. I have seen enough culture, antiquity and churches (that's where all the good art is) to last me for quite a while. While DH was taking pics of sculpture and paintings, my camera was pointed a different way (more of that later!) Before this trip, I googled fabric stores in the areas we were visiting. Unfortunately, in Italia, you can buy Armani suiting but not quilt-type fabric.
I would suggest Googling the areas you are visiting and perhaps also asking at the various hotels you will be staying. Have a wonderful time!!
