Alright so I want to camp out in a certain area and wait for something I'm pretty sure only happens at night. So how do I make a fire to sit by?

I'm pretty sure it has something to do with my wood bundles and my flint, but I dropped my wood on the ground and can't figure out how to use flint to create a fire in the wood.

What are the ways that I can start a fire (to sit by/pass time at) at whatever my current location is?
