I learned how to make my own laundry soap yesterday at a fun class that went to! It ends up being about .07 cents a load! You only need 2 TBS. per load and it smells great!
Here is the recipe:
2c. Fels Naptha (or 1 bar)
1c. Washing Soda
Cut up the Fels Naptha into thin slices and smash it a little bit with the flat side of the knife. It will crumble a little bit and then it is easier to blend up.
Measure the rest of the ingredients and blend them up!
Store in a glass jar and EnJoY!
