I have been making candles for a little over a year now and have tested,tested,tested. I had THOUGHT that I finally found the right wick selection. I have been burning the same f/o and hae made it the same way numerous times over the past year. I just started burning this candle a few days ago and noticed alot of hang up which NEVER EVER HAPPEND before with this formula. I am beside myself thinking that what I thought I had achieved after all the testing and money in the last year is not right all of a sudden. I figured ok maybe a draft so I moved it to another room and it never caught up. I am now more that half way through a 10 oz candle and its getting worse. I know its best to wait until its done to see if it catches up but its downright looking ugly and not up to my standards. Could it be the temperature change? Its only been hitting 40 degrees and thought maybe thats it? I am confused!!! I am using 10oz status jars, 415,1 oz f/o per pound and CD-1O'S. Any ideas? Mike
