I saw some candles at a booth last week that had wicks that stood up out of the wax about 2-3 inches, they were long!! A few were off center too, I don't get it.
I am looking to replace the rocky mountain pine also!! Naturally Tru have you tried ICS classic cinnamon buns? I don't know if it is like HF but it is good!!!
I agree try another wick, the differences in temp and humidity do affect your candle but I don't think it will be a major factor when you burn it all the way.
I don't make pillars, sorry. I hav eonly dusted the tops of container candles: heart dishes, Xmas candle container candles, etc. I bet it would look great on a pillar. AH/RE probably have instructions on how to do it.
