This is a recipe that I found on a blog that was referred to me. I will keep you posted on what I think of my own soap. I used an oatmeal natural soap that we have a lot of and that we use for ourselves. The only thing I did differently is add Solumel from Melalueca to my batch. The cost per load is about 1-3 cents a load.
The recipe is:
3 oz. grated soap
½ cup washing soda(do not use baking soda instead)
½ cup borax
