Several years ago I took a class from Lori Nova (Endres) of The Nova Studio on how to make your own bath salts, body scrubs, milk baths and tub teas. We learned how to make a milk bath recipe that was very simple and packaged in a very cute way.
As I follow the Soap Queen's blog - Soap and the Finer Things in Life - Anne Marie posts a very different recipe. Her recipe includes cocoa butter and pink sea salt. This is a recipe that can be included to your bath products library. Give it a try and let us know what you think.
