I also make my own laundry soap using my own liquid castile soap (grate the soap, add water & wait 'til it melts - no need to heat). I use only 1/2 cup or less per load and add a tbsp or so of washing soda. No essential oils - sunshine & fresh air smell best! Occasionally, I check the laundry detergent aisle of the grocery store. There are none that aren't 'scented'! Hate those artificial fragrances!
But how did the elephant get like that? What did you do? I think all we can do now is read this tiny ad:
