I said it might not happen, but it did: your comments totally influenced my Architecture challenge decision, and deck stairs and geraniums it is. Here's the original photo (left) and after some Photoshop play (right), so I have something more abstract to work from:
"After" is the result of several rounds of copy/paste/flip/rotate/scale, followed by application of the "dry brush" effect. This would make a lovely quilt at, oh, 60"x72" or so, but is now way too complex for a smaller work, so I'll be sampling in some way.
I've not yet started working with fabric, other than to acquire yardage, as this palette bears no relationship to my stash (other than those pops of bright red!). A wildly fauvist approach to color would be fun but is not where inspiration is leading. All those grays will be giant step away from usual for me, so that's what I'll be doing. This required a stop in at my LQS where I spent 3X budget for pale green and gray fabrics, including a "Bali Pop" jelly roll ranging from ivory to black that will be very useful.
Of course, even a fistful of fat quarters and a Bali Pop quickly adds up to more yardage than a small quilt needs, so my insanely over-ambitious muse is whispering, "a triptych could be fun."
Sometimes I wish she'd just shut up or go bother someone else for a while. I'm aiming for one and we'll see what happens.
