Step 6: Let It Age
Once you are happy with the fragrance that you've created it is time to let it age. Place it in a cool dark location for a minimum of 48 hours, up to a month.
Aging your fragrance allows the scents to mingle, and also become stronger. Once you have aged your fragrance for the desired length of time, smell it again, the mingling may have changed the overall scent, so feel free to add a few more drops of scent to tweak it (don't forget you will need to age it again, if more scent was added).
