Otis I went to the generations site and this is how I saw it. it is the Snail Trail block surrounded by the sashing that is on the site as a template download. At the end there is a link for the Storm at Sea paper piecing quilt block and click on it and it will fit this Snail Trail block at

The Snail Trail block will finish at 6 inches and so will the sashing.
