Friday Night turned Saturday Morning

The best part of the week came Friday morning, in the form of a telephone call informing me that I no longer have to work overtime. Which is really, really great, because it was honestly getting quite difficult to take care of everything. (Bending over and reaching into a knee-high metal box with a pair of pliers and a screwdriver? With 20 weeks of baby belly? Not fun.)

So this evening, I intended to work on the baby quilt. The backing fabric I ordered arrived in the mail, I had everything pressed and laid out and...well...

 ...it's pin-basted! (That's something, right?)

But I have no idea how I should quilt this thing.
Should I go for just a stitch-in-the-ditch, and let the fabrics show? Should I make parallel diagonals? Should I stipple? Or bubble-quilt it? Or something else entirely?
Unfortunately, Tim is zero help on this. He usually gives color approvals or vetoes designs he doesn't like. But that's it.

So, any ideas? (Seriously, I need suggestions.)

In the meanwhile, I've got a crochet afghan I can work on...
