Thank you to Ryan Jordan who suggested using blue shop towels as an alternative to toilet paper. This also works brilliantly as firestarter. A 1"x1" square frayed around the edge and balled up easily ignites from a flint striker.
Forget carrying cotton balls with vaseline or any other 'single-use' tinder. Just smear some Carmex (which I already carry for its obvious use) into the piece of towel. OR, add a couple of drops of Purell alcohol gel (which, again, is already carried for its obvious use a hand sanitizer). Now that same piece of towel will burn for about 30 seconds.
But if you really want flame, add a couple drops of 100% deet (again, now a multiple-use item) and that small piece of towel will burn with a 5-inch flame.
Pretty cool!
