Just a few years ago, all Katie Daly knew about candles is that they smelled nice, and she liked having them around the house. Her boyfriend, Cody Weiss, didn't disagree. But Daly, always a self-admitted "type-A antsy person" found herself bored and browsing Pinterest one day, when she saw a how-to guide to making soy candles in Mason jars. The corporate trainer melted some wax on the stove, adding some lavender oil - and found herself surprised when the candle actually burned.
