DIY Laundry Detergent

Today on Pinterest I ran across a recipe for DIY Laundry Detergent. I must try this. We always save the cat litter buckets so I'm sure I could mix some of this up in one of those or in a giant bowl and then I could make laundry detergent once a year and save not just money, but I won't be buying all those plastic and cardboard containers that laundry soap comes in. If I can talk my boyfriend into doing it this way, I'll let you know how it goes.
