Saving Money in the Laundry Room

My husband's friend makes his own laundry detergent.  And we were thinking we would try it to save some money...but it has to be boiled and that just hasn't sounded very appealing (and I haven't needed any more until now), but I found this recipe for powder laundry detergent.  Looks pretty easy, and it's basicly the same stuff that is in our friend's liquid detergent minus the boiling water!  So while I'm out of town this week, I'll be off to the store.  I'll let you know how it all turns out.
