I do like them and have burned them. I have to be careful though, because of my lung problems. I think I really like cinnamon. I remember rose potpourri and loved it though it didn't last long. If I found a rose candle I'd keep them around.

I've heard that if you burn candles, always look behind you as you turn out the lights in a room to make sure no candle is burning. I usually just put a lid on them and the go out quickly.
