Yeah, that's the Tennessee Waltz pattern the only thing that differs it from mine is the star in the "snowball block". These quilts are gorgeous and look like they are curved lines when actually everything is straight pieced. Gives a beautiful illusion and contrasting color choices make this quilt a "wow".
It is made with only two block, the 54-50 block http://www.portup.com/~hjbe/quilt/54-40.html
and one snowball block http://www.straw.com/quilting/articles/snowball.html
alternating between each in the setting.
I would love to see this if you decide to make it!
