Tie a simple overhand knot in the yarn at the base of the match head, and wrap the yarn down the shaft. Tuck the tag end under the last wrap and pull it snug. Cut excess yarn.
Melt paraffin wax in a D.I.Y. double boiler: Select an old pot that will nest in a larger pot. (A clean coffee can will work in a pinch.) Fill the larger pot about half full with water and place over medium heat on the stove. Put the wax in the smaller pot, which goes inside the larger pot. Pay close attention: Paraffin wax has a low flash point and can burst into flame when overheated. When fully melted, move the setup off the heat.
Insert a straight pin into the non-striking end of a yarn-wrapped match, and dip for a few seconds into the wax. Set the match on foil to harden. Dip each match into the wax several times to build up a waterproof coating that will also serve as fuel. After the last dip, remove the pin and tamp down the moist wax to seal the pinhole. Or Make A Simple Pocket Fire Starter
Bottle-cap fire starters provide the strong, long-lasting flame that ensures ignition of fine kindling. Small and convenient, they are great for stuffing into pants or jacket pockets for emergency use.
