Melissa Borrell is a very interesting designer.
She makes beautiful window shades and her unconventional "pop-out jewelry' is gathering a cult following.
Here's another wonderful product from her.
Her 5" diameter etched glass shadow bulbs are beautiful.
They are pricey at 90$ a piece but think of the money you save without having to buy a shade!
They make stunning shadows.
She sells lamp bases as well on her site here.
