The best way to start learning, IMO, is to find your local glass shop and ask if it is ok for you to sit and watch the artist work, packing bowls for him never hurts. After a few weeks of this you will be at the point where you understand the process and think it looks easy. You will tell yourself, "I can do that shit." Then if you are lucky you will get the opportunity to hop on a torch, where you will immediately discover that you know nothing as the hot gob of glass flails uncontrollably in your hand. Now you are ready to learn. Good practice is to dip a pencil in honey and pull it out, now spin the pencil so no honey drips onto the floor. That is a good way to get your hands and eyes on the same page as well as an introduction to gravity as it pertains to glasswork.
