I love these colors together!
No, the back isn't gray, I just removed the color to show the quilting. Since I took pictures at night (yes, really), it was the only way the quilting would show up.
See my previous post for all the details about this quilt.
Stats: 12 FQs of It's a Hoot, a little less than 1/2 yard for binding, and 1 3/4 yards of Cyan for backing = 45"x 60" (pre-washing)
