craftgrrl | Fragrance vs. Essential

Hi! I was sent here by

quietexpression and so far it looks like a pretty nice community!

I have a million and one things I want to learn how to do but candle making is going to be one of my first. My question is:

Does it matter if I use fragrance oils or essential oils when making candles at home? I know of a store that sells essential oils for a certain amount per ounce but most of their fragrance oils are $2.50 an ounce. What happens if I use fragrance? Will the scent come through still? Or will I waste my time?
