Now is the big reveal of which layout I chose, it wasn't either of the ones shown initially, but it is an organized one; I couldn't get any random ones to look right.
The quilting itself is an all over stipple, and I'm using a turquoise to white variegated thread from Aurifil.
Update (8 hours later): The entire top is quilted. There's one small pucker on the back, but since it's Minky it's not very noticeable. I'm quite pleased. Spray basting is definitely my new, favorite quilting tool. If Only I'd learned of it sooner.
