Who knew? Well, okay, someone, but I wasn't paying attention. Back in the day, I used to scent my own laundry detergent with essential oils. Oh, I could get all boil, boil, toil and trouble with my potions, adding in that which would calm, or kill bacteria, or smell good, or some combination of that or other.
I'd avoided thinking of doing that with a perfume...potential allergans, cost return for amount of edp required to scent a batch of clothes, etcetera. Though it did occur to me that a good elixir might be cost efficient.
Now this news of the Le Labo/Laundress product has opened a whole new series of ruminations: Diorella, laundry scent? Chergui on the sheets? Kingdom on the unmentionables? (Might as well...)
Nah. For now, I enjoy dabbing or spraying my personal scent. And that's part of the trick, isn't it--personal scent can't come out of the batch laundry. So, back to nothing, or maybe a simple lavender, when it comes to scenting the laundry.

If I have my data correct, you can make a basic laundry powder out of basic soap, borax, and baking soda. For examples, see The Simple Dollar, or the variations on a recipe at TipNut. There are green cleaning books that have recipes, too. Creating my laundry soap is a time investment I'd rather devote to other projects, so I have used premade product such as Moonworks, which will ship to you with no s/h fees.
I also found a post and discussion of the LeLabo/Laundress product over at NST last March. Robin's got a great blog; I'm there all the time.
