The Blue Heron Glass gallery (on Old Towne Road) offers classes in the glass arts, such as stained glass and fusing.
The class schedule is conveniently online. Most classes are held in the evenings and cost anywhere from $50 to over $250, depending on the number/length of sessions and the materials involved.
The one notable requirement to attend: don’t wear open-toe shoes. (Something about gravity and its effects on glass.)
