Please note:
BODY TEXT*
is the most com­mon
el­e­ment of a doc­u­ment.
There­fore, how the body
text looks will have the
most no­tice­able ef­fect
on the ap­pear­ance
of the doc­u­ment.
Con­se­quently,
you should
set up the
body text
FIRST.

Start with
font, point size,
line spac­ing, and
line length, be­cause
those four de­ci­sions will
largely de­ter­mine how
the body text will
look. OK?
