Thanks, guys!
I'm lookin at it like a "wheel" of 6 with six spokes.
I think it's true that I'd really need nearly 600 petals! D'oh!
I'm using freezer paper, glue stick to fold over, then attaching by machine, then machine quilt.
I've got a scrappy orange motif going on, but I may need to broaden that base if it looks a little too monochrome. So far, I've got 17 fabrics.
So far, I've prepped 70, with about 40 waiting to be turned. Then I've got another 50 freezer petals cut out, with another 50 waiting to be cut.
