I am making a board game and I have created mission cards and vengeance cards
which already have the necessary proportions templated due to creating them
in the business card format offered by Microsoft Publisher.  How do I find a
basic template that has the proportions of 10 business cards on 8.5 x 11
paper so I can paste different information in each slot on the back of these
game cards?  (I don't want 10 copies of the same mission written out because
the template automatically duplicates.... I want a raw template.)  All advice
and tips are appreciated.
