Scrappy Stars Backing Fabric Found

This is what I'm using for the backing of Scrappy Stars. It came as a surprise to me. I was looking through my stash for navy or black fabric, but the pieces weren't big enough without having to piece together. I looked in another room, where I was sure I could find some navy yardage. That's when I found this beach umbrella fabric, which I bought years ago, and brought out just recently for an undetermined summer piece. There was more than enough for backing.

The front of the quilt is Fourth of July by night, and the back is Fourth of July by day. How much better could it get?
