I'm assuming you're building your fires in the more "traditional" way, something like this:
This method has a few drawbacks... I'm guessing that you're looking to light your fire from the front and back in the hopes of getting it to burn evenly to prevent it from collapsing in on itself and smothering right?
Rather than changing the way you light the fire, consider changing the way you build it to begin with. There are a couple of fire building methods that should light easily without requiring you to light it from the back.
- Try the Top Down Fire:
In this arrangement you should be able to light the paper at the top-front and the flame should quickly spread all the way back and then slowly burn downward. The whole stack should light in about ten minutes.
- Try the Box Fire or Log Cabin Fire:
In this arrangement you light the paper at the bottom-front and the flame should spread down the middle to the back pretty quickly.
Both of these methods should give you a nice fire without too much babysitting. Adding more wood to these fires will also be easier because you're working with a flat top, so there's no need to carefully place and balance new logs.
