You can also use pgfornaments; a little example taken almost verbatim from the package page:
\documentclass{article}
\usepackage[object=vectorian]{pgfornament}
\usetikzlibrary{shapes.geometric,calc}
\begin{document}
\begin{center}
\begin{tikzpicture}[color=red!50!black,every node/.style={inner sep=0pt}]
\node[minimum size=10cm,inner sep=0pt](vecbox){};
\node[anchor=north west] at (vecbox.north west){\pgfornament[width=2cm]{63}};
\node[anchor=north east] at (vecbox.north east){\pgfornament[width=2cm,symmetry=v]{63}};
\node[anchor=south west] at (vecbox.south west){\pgfornament[width=2cm,symmetry=h]{63}};
\node[anchor=south east] at (vecbox.south east){\pgfornament[width=2cm,symmetry=c]{63}};
\node[anchor=north] at (vecbox.north){\pgfornament[width=6cm,symmetry=h]{46}};
\node[anchor=south] at (vecbox.south){\pgfornament[width=6cm]{46}};
\node[anchor=north,rotate=90] at (vecbox.west){\pgfornament[width=6cm,symmetry=h]{46}};
\node[anchor=north,rotate=-90] at (vecbox.east){\pgfornament[width=6cm,symmetry=h]{46}};
\node[inner sep=6pt] (text) at (vecbox.center){\Huge Ornaments};
\node[anchor=north] at (text.south){\pgfornament[width=5cm]{60}};
\node[anchor=south] at (text.north){\pgfornament[width=5cm,symmetry=h]{49}};
\end{tikzpicture}
\end{center}
\end{document}

And, of course, you can control the attributes (including size) using the options for \pgfornament:
\documentclass{article}
\usepackage[object=vectorian]{pgfornament}
\begin{document}
\begin{center}
\pgfornament[width=1cm,symmetry=h]{49}
\pgfornament[width=5cm,symmetry=h]{49}
\pgfornament[width=10cm]{49}
\end{center}
\end{document}

Processing the following code, you'll get a four page document showing the 89 predefined ornaments:
\documentclass[twocolumn]{article}
\usepackage[object=vectorian]{pgfornament}
\newcounter{ornnumb}
\begin{document}
\noindent\loop
\ifnum\value{ornnumb}<89
\stepcounter{ornnumb}%
ornament~\theornnumb: \pgfornament[width=1.5cm]{\theornnumb}\\[1ex]
\repeat
\end{document}
\includegraphicscan used to include vectorial graphics (eps, pdf) which can be zoomed to any size. – Javier Bezos Oct 05 '12 at 16:28\includegraphicsis that I am not willing to pay for high-resolution ornaments just for decorative purposes :) – CherryQu Oct 06 '12 at 12:48
