Love my new lamps!   Many compliments on them.  
Take away is having to “build your own lampshade.  Not real hard to do however, I’m very fussy about the evenness of shade fabric over the metal. 
AND, typically you’ll have the rim at the top and bottom of the shade covered with the same material as the shade itself.  Meaning, you don’t see the silver ring around the top.  I feel it takes away for the look - cheapens the look of a beautiful lamp.  
I’ll keep my eyes open for new shades; adding another $100.00 to the total spent on them.
