For your carrier oil, you want an oil that has a neutral smell that does not go rancid quickly. Some options include:
Sweet Almond Oil
Grapeseed Oil
Jojoba Oil
Olive Oil
Fractionated Coconut Oil

If you want to make a solid perfume, use equal parts carrier oil and beeswax. Melt together gently and then add fragrance and pour into container for storage.
Top notes: 3 drops
Middle notes: 2 drops
Base notes: 1 drop
The top notes are the most pungent and volatile. They act quickly and disappear quickly, and their first impression only lasts for about 30 minutes. They stimulate and uplift.
The middle notes are more stable. Their scent unfolds anywhere from one hour to three hours after application. They soothe and balance the body, and they round out a blend with softer tones.
