We had a treat. Helene arranged for us to meet Alberto Valese and go to his home/workshop to see him make marble paper. I had directions to the meeting place but in Venice it is easy to make a wrong turn. I thought I was going the right way but I didn't see Alberto. Fortunately Helene had enough foresight to give me Alberto's phone number. So, I called him and was trying to explain where we were. He said "Are you wearing a yellow shirt? I was! He waved and that was that. Alberto led us around corners, through narrow streets and before long we were at his place.
