Bonfire with a strong flame in form of a hut in which puts board in winter. Collect material for kindling. Bonfires need a broad surface, lots of tree and a bit of tinder. So it will be easier to ignite and have permanent heat and blaze. Good fuel for fire cardboard boxes, large pieces of wood, cut into small pieces and sticks with shavings. And laid timber in ring. They should be placed close enough to each other, and at same time between them should be enough space for air circulation.
