Hi Everyone, I've been reading these boards for several months now but this is the first time I've posted. I'm just starting out with candle making and I really love it. Today I'm going to be trying some layered candles - votives and containers - and I've never done these before. How long do I need to wait for the 1st layer to cool before I pour the second one? I'm not looking for it to be a super-clean line, a little minging of the colors would work. Thanks and I look forward to 'talking' to you all more in the coming months! Kristen
