Willow & Sage by Stampington
You will need
Wooden diffuser sticks
Lavender essential oil
Tea Tree essential oil
Fractionated Coconut oil
Blend essential oils into fractionated coconut oil at a ratio of about 1-4, fill glass bottle halfway and insert sticks.
Use a bottle with the smallest opening possible, and use as many sticks as you can fit into the opening. This will discourage oil from evaporating quickly through the bottle opening and encourage it to evaporate more slowly through diffuser sticks.
Display the diffuser far away from sunlight, strong lights, and excessive heat to increase the longevity of the oil blend, or display closer to these things for a stronger and shorter diffuser.
