Another opera balloon shade

It's flat when fully lowered, and pulls up dramatically, magically.  I left it hanging in the workroom for the decorator's twins, four and three quarters years old by their reckoning, to see when they accompanied their mom to pick it up.  They were enthralled by the shade.  And I was enthralled by them.  I wish I'd taken a video of them raising it!
See how the pattern laid out?  The blue flowers are arranged nearly symmetrically.  That was the purest luck!  The board is 65" and I had 2 widths of fabric to work with.  There were no choices to be made about how to lay out the pattern- it could only be how it was.  Luckily the eye-catching blue is the most perfectly placed.
