Scope out your yard or walk your neighborhood to find pine cones. Collect pine cones of all different sizes and prepare them to be scented.
Clean pine cones by immersing them in water with a small amount of dish soap. This ensures that any stowaways are removed! Rinse and shake out excess water. You may notice your pine cones have closed after being immersed in water, but these will return to normal during the drying process.
