Glass Addicts provides a great introduction to stained glass for a "first-timer." You need to bring nothing, as all materials and tools are provided. You will be surprised at how quickly your first masterpiece comes together. The four-class intro has been a great way to learn the basics, and for me, to determine whether this is something I would want to continue. The owners are very supportive, hands on teachers who make sure you get off on the right foot. They are true glass artists, enthusiastic about their art.
