I use partylite candles in my house. I also like Pier 1 candles. Partylite candles burn pretty clean and dont make my walls black. The scent is there but not overpowering. I love lighting the 3-wick candles, its almost like having a fire place going!
The 3-wicks are pricey but well worth it in my opinion. If you hug them like it says too and burn them for 8 hours at a time like it says too, that candle burns down flat so you really get LONG life out of it!
