Any interest in candles? I am a consultant for Scentsy. We sell wickless candles. Instead of a flame, the highly scented wax is melted by a 25watt light bulb in a decorative warmer. Currently, there are 45 warmers and over 80 scents to choose from! We also offer room sprays and car candles in all of the scents. The stuff smells SO good. When I turn on my warmer in my dining room, I can sometimes smell it all the way upstairs!! The wax is only warmed, not burned, so there is no soot. It only heats up to just above body temperature, so you can stick your finger in it and it won't burn you. Of course, using a light bulb is also much safer than a lit candle. It is a great alternative to candles, especially if you have kids or tend to accidentally leave candles burning.
If you want more info, or have any questions, feel free to email me :) I'd love to help you out.
