The quilting design is my downfall in the process. My technical skills are ok, but I just don't have the knack that some people do for the 3D aspects of quilting. I also prefer less quilting and thicker batts than is currently popular.
I'd probably match the thread with the red and do an all over edge to edge sort of simple wavy tile pattern. The quilting will show some in the prints and simply hold the rest together.
For a more intricate design, I'd probably go a golden tan color thread that would disappear more into prints but show in the red.
