So I'm in the process of testing some tarts for a Nov show! I've got tons of time, it feels so good! LOL! I spent the entire weekend pouring after a long haitus (move-the movers lost and then found all my stuff a few months later!) Annnnyhow, do you melt for a few hours, then turn off? Do you let it burn until the scent is gone? Do both? Does it make a difference? Do you do 1 cube or 2 at a time? I've been doing 1, but after some reading, see a lot of people do an oz at a time and that would be 2... With my vanilla lavender, I got a good 6 hours out of 1 cube, but am a bit bummed. I can get days and days out of one cube in a plug in though. I'm assuming I'd get longer out of 2 cubes, but didn't want to be phishing for better results, kwim?!
