hey molly, i'm so glad you called me the other day too. it's amazing how we can always pick right up where we left off, isn't it? i too wish we lived closer to each other :)
the laundry soap recipe i used can be found at: http://www.thefamilyhomestead.com/laundrysoap.htm
i have found this same recipe on multiple sights all over the internet. i've been using it for almost a year now and i'm pretty pleased with it. and i think that i will be able to continue to use it on the baby's clothes and diapers. however, there is some concern that it may affect absorbency of the diapers and i might have to try something different if it doesn't work.
