Ravelympics ponderings

I'm trying to decide what I want to do for Ravelympics this year. I had originally planned to make badly-needed new slipcovers for the throw pillows on my couch. I was planning on winging it with some sort of cable pattern, under the theory that one shouldn't have to have a pattern in order to knit four 16" squares. I even had yarn purchased - Cascade 220 in a nice medium green.

Then, I bought a quilt. Specifically, I bought a blue and bronzy-brown quilt (go Ravenclaw!) with the intention of using it when I'm on the same couch that needs throw pillows. It only occurred to me when I actually saw it in the room that when you put it with the blue carpet, brown couch, and blue recliner, things in this room are actually starting to match... or at least to center on a color palette. I didn't pick the carpet and the furniture is from two different sources so this is more a happy coincidence than an intentional decoration scheme, but I'll take what I can get.

What would you make with 1,320 yards of worsted weight green wool?
