This activity is a weekend win with the kids. Go out and gather some pine cones, make sure they’re clean before laying on a foil lined baking sheet. Bake at 200º F in oven for about 30 minutes. Wait for them to cool and transfer to gallon zip-top bag. Add about 30 drops of your favorite essential oils and leave bag sealed for 1-2 weeks. The longer you wait, the stronger the smell. Place out just in time for your holiday celebrations.
