If you're using a taper, you want the very top of the wick to just reach the top of the mold. If your taper is too long (as mine is here), you'll want to cut a bit off of the bottom. Otherwise (like I had to do with this one), you either have to cut or melt the tip off. Here's a picture of the candle with the top melted off.
