Alright, so you know who you are....here's the recipe that I am currently using for Fabric softner.
1 cup baking soda
6 cups white distilled vinegar
8 cups water
10-20 drops essential oil (optional)
Mix above in LARGE container (will bubble like CRAZY!!!) and store at room temp. When using, give a shake or stir to mix the essential oil back in and use 1 cup per load.
This is VERY cheap, works GREAT and leaves no nasty vinegar smell (I was skeptical, but it's true!)
