I started this thread back in 2008, and so far no one can do it cheaper then I.
It seems like most people have to buy something to make Fire starters. Just this week end i gave a bag full a way to a camping friend that gave me some old candles and some cardboard egg cartons. Over the winter i have collected more candles, egg cartons and saw dust and i will take them to the campground and make some more over an open fire on the fire ring.
For the amount of time since i have been making them, i have found on negative drawback, they are water proof, safe to store anywhere, smell good and never go bad and safer then using additives like fuels to material.
I ask people if they have any old candles and if they buy eggs in cardboard cartones, if so then i will take them off of there hands for free.
