Far easier and cheaper than this is a VERY simple trick that anyone can do for a few cents each. Go to most any Dollar Store and get a 50-ft length of 1/4-inch (6-mm) diameter COTTON (MUST be Cotton ONLY) clothesline. Now, at home, cut it into 1-inch long segments until you have the desired quantity. Warm a small amount (2-3 tablespoons) of Vaseline (or other petroleum jelly) until it melts (over a safe, non-flammable hotplate or surface). Now, using a steel fork, slowly drop the cut cord pieces into the pan, gently stir and press on them until they soak up the Petroleum Jelly (it should be like warm cooking oil in fluid nature when warm), then with the fork, carefully pull them out and place on a clean pizza pan or cookie sheet to cool. When cool, they will congeal until like 'greasy bacon'. Place them in any Polyethylene container (plastic, like a vaseline jar or small butter tub), and use them as you need. Pull one out at a time, light it with a lighter and quickly place into your kindling to start your fire. They will burn 6-7 minutes robustly, and with a good ferroceramic stick, they will also relatively easily light as well. Super-easy to make, easy and cheap to make a lot of them, and safe to store (ziplock bag will work, and a one-quart bag can hold hundreds).
