IIRC, I just whittled a little off the end to taper it slightly.  In my case I drilled all the way through the leg so that it would come out the other side but for something where you might not want it to show you could stop short of going all the way through so it would only show on one side.  Chris Swartz has a good tutorial in his free Anarchist Workbench ebook.
