Hello,
I just want to put a quick suggestion hare: IMHO, making a campfire should be somewhat harder than putting 5 sticks together.
I'd suggest something like
1. 2-5 Sticks
2. A Flint
3. Old, dried, grass.
which will yield in high success rate to start a fire
or: sticks and some bigger wood chunk (hand drilling) with low success rate
or: sticks, wood and bow drill with medium success rate. Making bow drill would require some threads (can be gathered from plants) and a stick.
What do you think?
Best Regards,
Artjom.
