sashing fun

Thanks for the sashing suggestions for my HR quilt. Here's what I've decided on, with Butch's obvious approval:I'm sashing in the orange, which I already adore. I was most concerned about the way it'd look next to the bright orange AB print (on the left) and the sherbert-y Flights of Fancy on the right. But I'm very pleased so far, since it makes the paler prints stand out more than I'm used to.
I'm using five fussy cut 3" squares for the corners. I've decided that the corner pieces will be the same all the way across, so the top row are the bikes, the second are the ice cream trucks, etc. I'm planning on a pretty wide polka dotted border (that plan could change). I'm also trying to think about something brilliant for the back. Maybe another solid?
