Romantic Candle How-To: 1. Punch hearts from a sheet of wax using heart-shaped craft punches. 2. While holding a single wax heart with chopsticks, heat the pillar candle and wax heart using a blow-dryer (this will soften the wax heart, causing it to adhere to the candle). 3. Repeat this process until you have attached the desired number of hearts to the candle.
