For a pyramid stack, build as usual up to within two or three rounds of
where drawing in commences, then draw in a little at center of sides and
ends to bring the curves to straight lines; keep the corners well out,
observing the form of a rectangle in filling the middle, and finish to
top.
For a Gothic stack, build an ordinary one until commencing to draw in,
then draw in the oval corners and build center of sides and ends
straight up. For an X stack draw in sides and ends; build corners
straight up. These stacks look very ornamental on a premium farm and
will save well, but take more time to build than ordinary stack tops.
