If you have Word 2002 or above, you can use the "Book fold" feature. For
earlier versions, see
http://word.mvps.org/FAQs/Formatting/BookletPrinting.htm. But note that if
this is just for the front and back of a single sheet of paper, I wouldn't
bother with any kind of booklet. I do these all the time, and I *do* use
columns. You have to put pages 2 and 3 on the first page and 4 and 1 on the
second. Naturally, this works well only if you don't need page 1 to flow to
page 2 (that is, it is really just a cover). For more on columns, see
http://word.mvps.org/FAQs/Formatting/UsingColumns.htm. The advantage of
columns over other solutions (table, text boxes, etc.) is that you can put
just about anything in a column that you can put in a full page (tables,
tabs, wrapped graphics, etc.).
I use three different kinds of layout for play/dance programs. For cast
lists (where there is a single actor/dancer for each part) I use
right-aligned tabs (character name on the left, actor/dancer name on the
right). For small groups of dancers, I still make them right-aligned
(inserting line breaks and tabs as needed to make more than one line), but
for larger groups (as in dance recitals, where all the dancers for a class
are listed together), I put the dance title centered on one line and the
names of the dancers in a centered paragraph below (first and last name
separated by a nonbreaking space and names separated by an em space so that
the lines break naturally).
For the production credits I usually use a centered arrangement, with a
right-aligned tab stop just left of the center of the panel and a
left-aligned tab stop just to the right of it (separated by about 1/4"). I
then put, say, Lighting or Props on the left and the name(s) of those
responsible on the right, again using line breaks and tabs as necessary to
add additional lines.
