I know this thread is a little old but in reading that web page they state towards the bottom that if you use flat wick you don't have to worry about "direction". I had seen another place that said to use flat wick in tapers. Now I was under the impression that square braided was the best to use.
I'm a bit confused now.

Ok, I see now that flat wick is recommended for paraffin candles and square braided wicks are recommended for beeswax. I was probably already told this detail by some of you fine folks...and I forgot it. ;) Ed
