Back in Pittsburgh, Carnegie Mellon had some affiliated classes with Pittsburgh Glass Center. Of course, the seniors had priority to register for them and openings were limited. I never got the opportunity to choose one as an elective. Instead I took calligraphy, which I haven't used since. Finally, after oh-so-many years, I found a workshop at a glass center called One Sixty Glass in Williamsburg, Brooklyn. It was a simple 45 minute introduction to glass blowing. Our instructor Isaac was very friendly and personable, as well as informative and helpful. Within the hour and half between Gary and myself, we came out of that class with almost a dozen glass balls. These make great Christmas presents for family and friends. Gary's parents put up a tree every year, so a few of these will definitely be seen on it this year.
