I have heard nothing about soy except that it eats fragrance and is hard to figure out. Clearly, I am not going to sell these if they don't even have a scent throw lol. I'm not trying to give myself a bad name..I am using RRD wicks, so far I have used pumpkin spice, blueberry muffin, creme brulee, sugar cookie, and cinnamon bun just to name a few. I let the candles cure for 24 hrs and did a test, no scent. I did another test after curing for 3 days, no scent. And I just tried one today that I made over a week ago, and there is still no scent throw. Their cold scent throw is amazing though! For the most part I am using votive molds for my testsers..any suggestions would be great. Thanks
