Natural Aromatic Christmas Tree ... It incorporates acorns, pine cones, cinnamon sticks, star anise, and whole cloves ... A cone made out of floral foam is used as the base. The natural aromatics are added using floral wire and pins. The aroma of the spices will fade over time, but can be freshened back up by carefully dropping essential oils onto the tree. Tiny twinkle lights would really turn this into a showstopper!
