That quilt was just made using the wonky star pattern, but interlocking the stars. You can find a quilt along for this style here:

It's a different take on a pattern that's been around forever. (The wonky star gained popularity when it was used for the Bush Fire Relief quilts some years back)
I hope that helps!!
