Start by opening your tub of Crisco. I bought "butter"-flavored because it was cheaper. And as an added benefit, my hands smelt buttery and delicious by the end. Next, cut your wicks to size. 2 large, 9in. wicks are perfect for making four wicks. I cut both wicks in half and slid them easily into the soft shortening. Four wicks will create a lot of light and heat. Finally, light your wicks. This candle makes a lot of black smoke. It's fine in an emergency situation, but I wouldn't use them to "set the mood." The candle will easily burn for more than 100 hours. 16oz. of Crisco is a lot of fuel for a candle to burn. After about 90mins, two of the wicks snuffed themselves out. No big deal. They were easy to relight. When you're done with the candle, just snuff it and put the lid back on. The shortening will solidify and it stores well for later.
