Glass provides a resting place for wine, evening wear for Cinderellas, and a more dramatic exit from 44th-floor windows for Bruce Willises. Shatter artistic inhibitions with today's Groupon: for $12, you get one introductory class at CJ's Stained Glass Concepts (a $25 value).

CJ's Stained Glass Concepts' workshops and full line of art glass help patrons shine shades of refracted light into their lives. The three-hour introductory workshop teaches students to make a handmade stained glass night-light, perfect for illuminating rolled-up carpet edges and prowling monsters. The class is taught by instructors who have created stained and art glass for more than 30 years. Classes are held on Saturday afternoons.
