The instructions for these lampshade patterns are provided with our styrene forms (purchased separately), and not with the patterns themselves. All of these patterns are intended for use with the copper foil method of construction.
These patterns are as accurate as it is reasonably possible to be in depicting a curved design on a flat surface, but as with any curved lampshade, adjustments must be made in making the patterns meet the requirements called for by the shape of the form.
The 18" diameter cone patterns fit our Styrene Form #2352, and the 22" diameter cone patterns fit our Styrene Form #2353.
The pattern titles followed by an asterisk (*) are adapted from a Tiffany Studio Design.
