Candle making is different from soap and even lotion making; it's extremely finicky and exceptionally time consuming - especially if you're using soy wax. There is no one recipe that works for everybody or even 10 out of 100 people because every tiny detail affects the outcome. What works for one person, will probably not work for you or me. I swear - even the type of utensil I use to stir the wax makes a different in candle performance!
I'm still trying to make a safe and decent wood wick candle (without scent - so should be even easier to accomplish, right?) and was given step by step instructions from a professional chandler with over 25 years of experience. She told me my candles would never be like hers, to expect to spend time tweaking it until it worked - because that is just the nature of candles!
Now, a person can always get lucky. But since you need something this Saturday, I think you're going to need a different plan than making your own.
