Grow a glass garden — and beautify any space with the exquisite decorative items you’ve created. George W. Shannon and Pat Torlen, two master teachers and artists who run the On The Edge Glass Studio, offer an array of glorious patterns for stained glass flowers, butterflies, birds, birdfeeders, planters, lanterns, and mobiles. Using dozens of close-up photos, they teach all the basics of both copper foil and lead came construction, from materials and tools to how-to techniques.
