To reiterate the recipe that can be easily found all over the net:
1c. Washing Soda
1 bar Fells Naptha grated fine
Sparing you the mechanics of the math (because I honestly don't remember how she did it :-p), the proportion comes out to 4t. powdered mix to one quart of the hottest water you can get out of your faucet. Stir til dissolved and let set 8 hours or overnight. Viola! You have a mini batch of home made laundry soap that (at 1/4c.-1/2c. per load depending on load size) is quick to make, convenient (the night before your regular laundry day), space saving and most importantly can be kept out of reach of curious little boys and their bugs, and tipsy toddlers!
And being hormonally forgetful as I am right now Ive actually made a weaker version of 2t. per quart and not really have a whole lot of difference on how well it works. In my 1/2 gallon pickle jar I usually put 5-10t. and have it come out wonderful. Really couldn't handle the snotty look at first when I forgot to stir it before pouring a bit into my quart jar and it just about made me loose it. Am going to try adding some essential oils to it here soon, and am excited about being able to change the scent of the mixture whenever I want, as I wouldn't be stuck with 5 gallons of a smell I or my family couldn't tolerate.
So I hope this helps with those of you that have space issues, or children issues and have been looking for a solution.
