I've just discovered Christine Kilger's handmade lampshades and am in love! She uses antique bases and vintage fabrics and embellishments collected from around the world to make her gorgeous one-off creations.
You can order one of her pieces from http://www.nightshades.com/, but be warned, they ain't cheap. Averaging at approximately $2000 per piece (+ $175 shipping) they're way over my budget so unfortunately I'll just have to admire them from afar for now.
