There are a few important things to know about "fancy" (i.e. patterned, non-neutral or otherwise embellished) lamp shades: First, they can make any lamp, sconce or other light fixture look infinitely more luxe. Second, they're surprisingly hard to find. (Ballard Designs is one of the few mass retailers that sells them; Etsy is also always a good idea.) Third, they can get ridiculously expensive (but arguably worth it if you have the budget!).
