I don't know if any of you have tried this, but everyone in my area loves it. I take pine cones, put refresher oil spray on them. Leave them in a bag for 3 days (shaking them up each day). After the 3 days, I put them in a basket, put clear christmas lights through them. And give with a bottle of refresher oil spray. You spray the pine cones once daily or every other day. The lights heat the refresher oil and you can smell it almost all through your house. I just thought I would share this with you all, because you all have helped me so much.
