This one, from a Tula Pink pattern:
I currently have two thoughts on how to quilt it...the first is to do straight line quilting in a square spiral like I've drawn below (except with straighter lines...excuse my Photoshop skills, but you get the idea!).
The second is to quilt each quadrant differently, similar to Tula's original pattern, except using simpler, easier-to-execute designs. I'm a little concerned my version might be too busy for this type of quilting, though.
I'm open to opinions and other ideas. What do you think?
