I have become the sort of person who makes their own laundry detergent from Dr Bronner's liquid soap (the nearest place to buy bulk dry detergent is very inconveniently out of my way pretty much ever, and also expensive). This is a problem when I finally round up all of the laundry and realize I'm out of detergent. Do I wing it with the bottle of Dr Bronner's plus a box of baking soda at the laundromat? Do I try to make more? Ugh...
