Keeks, I couldn't use a tool. It kept messing me up when I was wrapping. I just use about a 3"-4" piece of the 3/0 candle wick (it's the skinnier of the 2 sizes you have). Fold it in 1/2 and start wrapping my coils around the middle. That ended up being the easiest way for me to build them. Once you have it positioned where you want it then you can snip off the excess wick.
