So tonight, we made laundry detergent. I haven't done the calculations yet and I'm waiting to see if this actually works. In the meantime, I'll share pictures.
These are the ingredients. I found these items at the grocery store in the laundry aisle. (Confession: As much as I hate that place, I checked "Wally World" first. They did not have all of these items. So much for one-stop shopping.)
