The ingredients behind every bath bomb, room spray, salve, and lotion bar in my house.
I used to buy a separate kit every time I wanted to make something new: one box for bath bombs, another for room spray, another for lotion bars.
Once I realized how much overlap there actually was, I started keeping these 11 ingredients stocked instead.
Now I can make almost anything on this list without a special trip to the store.
Because you shouldn't need a cabinet full of single-use kits just to make the stuff you actually use.
