My first Post! I'm very new to candle making, so bare with me. I've used the "official" fragrances made by candle the candle suppliers to make some candles. But I saw that Wal-mart has tons of fragrances in there store. Had anyone used those and are they any good? How much do you have to use per gallon if they are any good? Just wondering. Its just nice to be able to run to the store instead of ordering online.
