Button, button...

At the urging of several friends, I have given in and created a Facebook page to "advertise" the classes I'm teaching at the gallery.  I am such a technofeeb and this was an enormous time-suck, but at last I have finished the odious task and now at least have the class list and a few pictures posted.  Does anyone know where to get the Facebook "button" so it looks nicer on my blog?  The "Facebook" thing looks kind of dorky.  But then, I'm feeling kind of dorky, so maybe it fits...
