-You can also use custom sized Harvey Balls:\\
+
+There are two variables available to the user to override the size of the Harvey Balls globally.
+\begin{itemize}
+\item \verb|\harveyBallsSize|, i.e. the size of the Harvey Balls and
+\item \verb|\harveyBallsLineWidth|, i.e. the line width used to draw the Harvey Balls.
+\end{itemize}
+Threse values can be changed using the following commands:
+\begin{itemize}
+\item \verb|\def\harveyBallsSize{0.85ex}|
+\item \verb|\def\harveyBallsLineWidth{0.2pt}|
+\end{itemize}
+Whereas 0.85ex and 0.2pt would be parameters, i.e. your custom sizes. Note that these are also the default values.
+\verb|\def\harveyBallsLineWidth{1pt}| and \verb|\def\harveyBallsSize{3ex}| produces:\\

+\item  \verb|\harveyBallsColor|, i.e. the fill color of the Harvey Ball and
