Step 3: Build your fire - wood
You can't light coal with paper* the wood layer is there for the coal as the paper is there for the wood.
Layer small pieces of wood (kindling) alternately such that you form a "raft". The construction should be a bit like a wooden-pallet, it is there to support the coal and ignite it as it burns. Criss-cross the wood so that it is in some way a structure and cohesive. When your paper is gone you want the wood to hold it's position rather than fall apart.
Choose a mixture of thick and thin. Thin will burn easily and produce heat, thick will sustain your fire and ignite the coal.
As a rough guide, aim for a cross-sectional area of about 1 sq inch maximum, but don't have the majority of your wood thinner than this.
What you see here is a bit more than "enough" - but it lit just fine. Not enough and you risk having to start again.
*maybe a massive amount of paper, stacked really high, someone show me in a video this if it can be done.
