Where are you getting your oils?
Are you letting your clams cure because soy has to cure for a while in order to throw well. Paraffin require much less cure time.
I get my oils from many suppliers and they all have great oils and they all have duds. Scent is also subjective. What I might call a light scent others may say it's strong. I get my oils from Aztec, Candle Science, Flaming candle company, Candle Wic, Natures Gardens, Indiana Candle Supply, Fragrance Buddy, Just Scent and Rustic Escentuals are my usual suppliers.
