"SatinDucky: I don't do tarts, but I am curious... why do candles need to cure for scent throw, but not tarts? " Well that's what I was wondering. I usually do like Fern and as soon as they're set, I'd pop one in the burner. I recently put one on that I'd had sitting in a poly pro bag for a few weeks and had originally been disappointed with. BUT...after sitting for 2 weeks I felt like it was stronger smelling. Of course, it could just be the whole candle nose thing. I was just wondering if anyone else did cure there tarts and if it made a difference.
