...making my own laundry soap! Several friends have suggested it, and after seeing prices of washing soda & borax (the two prime ingredients), it would be stupid of me NOT to try it... especially since these recipes don't look time-intensive or hard! (especially making the powdered variety)
If anyone else wants to try, here are two sites! Making Homemade Laundry Soap and 10 Homemade Laundry Soap recipes.
I have read you can also add Oxyclean to the mix if need be... or I guess you could just throw it into the washing machine as usual.
