Hi and welcome. This might be a tough question, everyone has different opinions and ways of doing things. There is so many different waxes, fragrance oils, suppliers. I think for me my go to place for most fo's and my tart wax is Flamming candle, but there are a lot of other suppliers i just get a few or just 1 fo from. Its trying a lot and weeding out the ones you don't like and what works best for you.
