For this project, I'm using a Peppermint-Thyme essential oil blend from Mint Meadow Country Oils. I think they have perhaps the best mint essential oils and blends in the country! (And lots of other great stuff.)
Gently pour the white base into the mold cavities, being careful not to disturb the green swirls.
Additional note: Mint fragrance and essential oils are very strong! You will not need to use as much as you do with other oils. Be conservative.
