Hey Pink, whilst searching for a lampshade (see entry below), I stumbled on one of Decor8‘s blog entry from Feb 07. This Spiegel cherry blossom covered lampshade that matches (probably the same cloth) as the ones you grabbed at Urban Outfitters! Very nice coupled with the fire engine red lamp base!
Currently on sale for $224! (Still a pretty penny involved huh!?)
Maybe you can DIY something to that effect!
