How to make old fashioned soap balls

I remember as a child that my mother had a soap dish in the bathroom with a couple of soap balls.  Soap balls are those rustic looking balls of soap that were big in the late 60's and early 70's. And I was looking for a site that had information on how to make them. Well, I found this article by Danelle Karth on How to make old fashioned soap balls.

In Danelle's article, she gives you a basic Oatmeal Soap Ball recipe and adapts it to the Melt and Pour and Hot Process methods.  I have not found any other recipes to share, but I am on the hunt for more. But I am sure that any rebatched or handmilled recipe would work just as well in this situation.
