Laundry Soap?

In an effort to be more natural and save a couple of bucks, I decided to try my hand at making my own laundry soap. I found the recipe on Pinterest.

...and you only need 3 ingredients

2 cups finely grated soap 

1 cup borax

1 cup washing soda

*use 1 tbs per load

(2 cups of soap = 2 bars)

Thats it, just grate the soap and combine the grated soap, borax and washing soda. I am currently storing mine in an old Classic pasta jar that I rinsed out and had on hand.

Have you ever made homemade laundry soap? If so what recipe did you use and how did you like it?
