The LQS has a quilt really similar to that I believe its an Amazon Star? Not totally sure. They sell is as a paper pieced quilt and teach a class on it. I tried looking it up but couldn't find it quickly...
Oh, I spoke to soon it's a Judy Niemeyer pattern called Agave Garden

Nope, just double checked it's similar though
