just a few tips.
soy wax has a memory. honestly. it will only remember the burn radius of its last burn. always allow your wax pool to reach the edge of your vessel. i recommend burning your candle for at least one hour (no more than 4 hours) to give your candle a long happy journey.
it's best to keep your candle wick trimmed to a 1/4 inch before each burn.
do not allow debris to inhabit your wax pool. be smart about where you burn your candle. keep it away from flammable objects, large bags of cotton balls, and your toddler.
never leave a burning candle unattended.
