Hi Shanda,
I love making candles. If you haven't already written about these, You can write about the difference between using essential oils vs fragrance oils or you can write about using natural ingredients such as soy and bees wax instead of paraffin wax and even using cotton wicks(bleached or unbleached) instead of wicks with wire, or using dried flowers to decorate the outsides of the candles. I am going to have to check out your site now as I must have missed it when I was skimming the list.
