I have no clue what to expect! Crackling, no crackling, bits and pieces in the wax, smoking wick, etc.... figured I'd give it a try though - that's the fun part! I am planning to purchase one of the WW candles as well this week to compare my finished product with theirs to see how they measure up side by side.... nifty concept that hasn't become popular at all in my area yet. I will be sure to post some pics.
