This 20-page booklet is a complete introduction to the Whittemore-Durgin Lampshade Construction System. It contains: - Illustrations of 102 different lampshades in color, with a listing of 172 patterns available for building them. - A list of glass requirements for all 172 lampshades - Illustrated instructions for making the lampshades on our sturdy full-sized Styrene lampshade forms. This booklet shows 102 lampshades in color, but because 70 of the patterns are available in two sizes, there are 172 patterns to choose from.
