The block measures 16″ because the orange peel collection contains a 4″ unit, making the center block 8″. The 4″ HST is available in the 12″ Storm At Sea collection and the centre triangle can be made by cutting 8.5″ rectangles and sewing the printed triangles to them. The sashing is 4×16″ finished with 4″ squares, which are found in the orange peel collections AND the 12″ Storm at Sea!
