Laundry Detergent Creativity

I've really enjoyed learning how to make my own laundry detergent...it saves so much money and is good on clothes. In this very materialistic and wealthy lifestyle, I find it incredibly satisfying to do what I can to save in the small areas. It's sortof like learning to cook good food instead of eating at restaurants...it just feels better. I thought this could even be a cute gift idea (assuming the person on the receiving end appreciates home-made...)
