The wife suggested I pour us some candles after we used up most of our store-bought candles during a recent power outage. I'm going to make some molds by carving out small logs but I don't know anything about pouring a candle. What kind of wax is economical to purchase that will perform well? And is the ball of cotton I use to tie up rib roasts suitable for the wick or should I buy purpose-made wick material? I'm only planning on making a small batch of these - not selling candles at a craft show (I hope)
