First, make a pine infused oil by adding the pine needles to a glass jar and cover with oil. Let sit for a few weeks, shaking every few days. Then strain.
Then melt the infused oil and beeswax in a double broiler.
Once melted, wait a few minutes for it to cool slightly before adding in your essential oil. Stir to combine.
Pour into your tins and leave overnight or until solid.
Notes
Any carrier oil works, I used avocado oil.
Pine essential oil is optional.
