First gather your ingredients:
Wal-Mart carries 20-Mule Team Borax
If you can't find Washing Soda at your local grocery
call the number on the Arm & Hammer box.
You can use Ivory soap if you can't find Fels Naptha
or I may have some available in the future.

I have made my own laundry for over a year now and this is how I do it.
