After shopping around unsuccessfully  in our small city for a shade that would measure 15 inches vertically yesterday Wayfair delivered the the right size and style shade for two beautiful hand blown glass lamps. Although the the shades are called 14 inches they actually measure about 15 inches on this nearly straight shade.  They give a lovely glow to the room at night  and look more expensive than they were. i am very pleased. 

Pros: No assembly.  A difficult size to find was quickly found online here.
