Thank you all so much!
I primarily buy supplies from CandleScience. They’re great and have A+ customer service. I have bought supplies other places, but always end up going back to CS because of the quality and care I get with them.
Fragrances tend to work for both soy and parrafin, but some work better/differently depending on the waxes, and some are optimized for use with soy wax. CS has great info and tutorials about scents, waxes, wicks, and the process - definitely check them out if you’re interested in candle making!
