One of the nice things about TeX is that you can put characters anywhere
you want on the page by playing with the spacing parameters.  One of the
not so nice things is that "Plain" TeX does not include some sort of
default definition of what doublespacing is.  I use the following macros:

% Single and double spacing, etc...

\def\doublespaced{\baselineskip=\normalbaselineskip	% reset to normal
    \multiply\baselineskip by 150			% doublespacing is 
    \divide\baselineskip by 100}			%  really 1.5 of normal
\def\doublespace{\doublespaced}				% synonym

\def\singlespaced{\baselineskip=\normalbaselineskip}	% reset interline space
\def\singlespace{\singlespaced}				% synonym

\triplespaced{\baselineskip=\normalbaselineskip		% reset interline space
    \multiply\baselineskip by 3}			% increase X 3

\def\widenspacing{\multiply\baselineskip by 125		% increase interline 
    \divide\baselineskip by 100}			%  by X 1.25
\def\whitespace{\widenspacing}				% synonym


Comments:  What I've called "doublespacing" actually only increases the
interline spacing by 1.5, but on a printed page it looks about like you
would want it to.  Actually doubling the spacing makes it too wide.
The \triplespaced macro, on the other hand, really does increase the
interline spacing by a factor of 3.  The only reason I can think of for
using this is if you print a draft and want to mark it up, so I leave
lots of space.  In the middle, you can say \widenspacing and it will
increase the current spacing by a factor of 1.25.  Unlike \doublespaced
or \triplespaced it does not reset the interline spacing to normal first.
So if you find my \doublespaced is a little too narrow for your tastes,
try \doublespaced\widenspacing.
