Fabric Softener = Vinegar and Lemons.
How? Take some white vinegar, cleaned sauce jars and lemons. Cut the lemons up and put them in the bottles. Fill with white vinegar, let sit in the sun for about two weeks. You're all done, now go do some washing.
Luky for me I grow my own lemons so I have them all the time, but you can also use plain white vineger as well. I mainly use the Lemon vineger for really bad smells and soiled sheets and clothes.
