What materials should you use when using the bow method to light a fire?

When using the bow method to light a fire, you'll need a bow (a flexible stick with a string), a spindle (a straight, dry stick), and a fireboard (a flat piece of wood with a small notch). The bow should be sturdy yet flexible, the spindle should be about 6-12 inches long and made of softwood for easier friction, and the fireboard should also be made of a softwood like cedar or pine for optimal results. Additionally, you'll need tinder (like dry grass, leaves, or bark) to catch the ember created from the friction.
