Whatever you decide to do, be sure to try it at home before you need it. Not all dryer lint burns, for example. Cotton sheets and sleepwear are treated to be fire resistant, so the lint is useless. Get used to what's available where you live, or where you hike. Some natural tinder items (i.e. cattails, fungus) aren't available everywhere, so you need to be able to work with what you've got, or pack enough ahead of time.
