How do I change the panel style in xfce4.8

[Sethun]

I've been placing themes in /usr/share/themes
and I've been able to change the window manager theme and the overall "theme" but sadly my top panel is still very bland and boring. How do I change it up?

I use 4.10 but this should work. Right click the panel, drop down to panel > panel preferences > appearance.
