Scrappy "Plus Surround" Quilt from 'Modern Plus Signs Quilts'

This is my completed "Plus Surround" quilt from the book, Modern Plus Sign Quilts.  There is review of the book on my March 29, 2018 blog post and discussion about making the quilt on the two subsequent posts.

There is straight line quilting on each of the plus signs which I really like. But I really struggled with how to quilt all of the negative space in this quilt (the yellow background). The quilt in the book has quilting radiating from the center of the quilt. I knew I didn't want to try to copy that. 

Because of the circular design, I decided to quilt the negative space with free motion circular loops. About half way done, I wished I'd done a misty soft linear/loopy fog-like design instead.  But it was way to late to do that!  The circular loops feel a bit too traditional for my taste, but it's growing on me! 

What's the best thing about this quilt? The great design of this quilt. It captures the viewer's attention!
