Planks
Wood that decided to be useful
Short answer
Sawn wood. Fences, crates, a fire if you're desperate.
Also: planks · lumber
How it works
Planks come from logs and work. They are bulky.
What to do
Saw what you need. Don't hoard a forest in a backpack.
Don't
Don't burn the only wall you just built.
