Now FOLD the unit in half along one diagonal, and stitch from the 1/4
point of the square to the outside edge of the hex, again
backstitching at beginning and end. Stitch the opposing un-sewn seam
in the same way, then fold the unit together on the opposing
diagonal and sew those last two seams from the center out in the
same manner. Add the four corner triangles to the slant sides, using
a scant 1/4" seam, and you are all done!
