title: In LaTeX, how can one add a header/footer in the document class Letter?
body: <p>In LaTeX, how can one create a document using the Letter documentclass, but with customized headers and footers?</p>
  
  <p>Typically I would use:</p>
  
  <pre><code>\usepackage{fancyhdr}
  
  \pagestyle{fancy}
  \lhead{\footnotesize \parbox{11cm}{Custom left-head-note} }
  \lfoot{\footnotesize \parbox{11cm}{\textit{#2}}}
  \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}}
  \renewcommand\headheight{24pt}
  \renewcommand\footrulewidth{0.4pt}
  </code></pre>
  
  <p>However, with \documentclass{letter}, this doesn't work at all. Suggestions are duly appreciated.</p>
  
  <p><strong>EDIT:</strong> Here is sample code that doesn't work (for any apparent reason):</p>
  
  <pre><code>\documentclass[12pt]{letter}
  
  \usepackage{fontspec}% font selecting commands 
  \usepackage{xunicode}% unicode character macros 
  \usepackage{xltxtra} % some fixes/extras 
  
  % page counting, header/footer
  \usepackage{fancyhdr}
  \usepackage{lastpage}
  
  \pagestyle{fancy}
  \lhead{\footnotesize \parbox{11cm}{Draft 1} }
  \lfoot{\footnotesize \parbox{11cm}{\textit{2}}}
  \cfoot{}
  \rhead{\footnotesize 3}
  \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}}
  \renewcommand{\headheight}{24pt}
  \renewcommand{\footrulewidth}{0.4pt}
  
  \begin{document}
  \name{ Joe Laroo }
  \signature{ Joe Laroo }
  \begin{letter}{ To-Address }
  \renewcommand{\today}{ February 16, 2009 }
  \opening{ Opening }
  Content of the letter.
  \closing{ Yours truly, }
  \end{letter}
  \end{document}
  </code></pre>
