Sue, I bought mine from my tiny local fabric store in Corinth, MS....But....taaadaaa...it is Nathional Parks Series- Arches # 2610 by Ro Gregg. www.northcott.net I think you'll be able to find it on line or at least I hope so. I bought it in March, so hopefully its not discontinued.
I also bought a darker more bronze looking color for the back of the quilt. I love it!
Good luck!
Patti
