...it smell good? We're supposed to use all natural ingredients.

At your local health food store there should be some essential oils for sale. Smell all of them )there will be like 30!) and find your favorie! It's rreally easyb this way since you have the scent premade and you could add some of your own stuff, too, like sugar you make it sweeter or cinnamon to make it spicier.

use herbs, flower petals, things that smell good in a grocery store.
