Sew Much Ado: Tutorial: Homemade Laundry Detergent:
This tutorial will guide you through the steps to make your own homemade powdered laundry detergent.
1 bar Fels-Naptha bar soap
1 cup Borax
1 cup Washing Soda
1/4 cup Baking Soda
*All of these items are found in the laundry isle next to the laundry detergents. If you live in Utah -- I had best luck at Winco for all the supplies, I was not able to find the Fels-Naptha soap or washing soda at the Walmart or Target in my area, but you may have better luck.
*If you try this recipe and like it, you can double or even triple the ingredients the next time you make it to get a larger batch.
