I have made this pattern too - it was very fun and easy - as for the backing - if you watch online you can get great deals on backing fabrics. Fat Quarter Shop has a daily deal that last for 24 hrs - usually the yardage is around $ 4.30 yrd or so or check fabricshopperonline.com - they list fabric deals usually on Saturdays from all over the internet - also I have found many great deals on etsy - just start searching for quilting fabric or specific colors - you will be surprised. I love your quilt, by the way, one of my favorite colors.
One more thing, try Craftsy, they often have great deals on fabric yardage and I have seen many Batiks on the site too - check back often with them.
