Your 6th square to mark off is . . . WICK DIPPER
Do you use a wick dipper every time you extinguish your candle? Or do you still create that smoky smell by blowing out your candle or turn your jar black by putting the lid on to suffocate the flame? Use those wick dippers! Have one for every room that you burn a candle in so that its convenient & you don't have to search for them!
