Did I really write "homemade matches"? Opps.I guess I shoulda written Strike on anything Diamond Matches that I waterproof with parafin wax. Just dip the whole thing in and let it dry. I've never had a problem lighting these-ever. Although, I'm looking at the REI type that are strike on anything and have about an inch of sulfur. I've seen the flame and burn on these and they are extremely impressive. The sawdust/parafin firestarters: Melt hard parafin wax, add hard wood saw dust (more like small shavings, not dust). Make mold outta aluminum foil about the size of a finger. Add thick wick the entire length and add wax/sawdust mixture. I get about a 10 minute burn time, and they burn in wind and rain pretty well. Try em and let me know what you think. The tarp is Silnylon 65" wide (it comes that wide on the roll) x 5' with all corners and mid points with sewn in loops.
