Thanks to my friend Shawna, I made my first 5 gallon bucket of laundry soap a while back.
She was kind enough to provide me with all of the ingredients I needed to make the soap, and this link for directions. All I had to do was spend about $6.50 on a 5 gallon bucket with a lid. Not too bad for 5 gallons of laundry soap.
And, the next 5 gallon bucket won't be that expensive either, because the only things I'll have to buy that go round are a bar of soap and some washing soda. I won't even have to buy borax, cause she gave me plenty for my next batch too!
This is quite the money saver, which is very helpful right now because I seem to be going over my grocery budget pretty regularly, though I'm trying to be better at that.
If you're not already making your soap - consider giving this a try. I think it'd cost you about $15 to get started (including all ingredients and the bucket) but the ingredients should last you for 4 or 5 batches (5 gallons each). And, if you already have some of the stuff laying around - even better!
