I have said e-cig, and i read on forums about making a replacement wick with 100% cotton yarn, I was wondering if i need to pull the yarn apart or just use the whole strand (diameter wise) also how long should i make it? does it need to touch the burner?

google brought me here, ive been searching for ways to make my own wicks and such so i figured i would stop in and check around
