DIsclaimer: this includes matches and hot wax, so be safe, don't burn yourself or your house down!
Step 1: Materials
-Match striker strip (should be in good condition)
-Beeswax (or candle wax, whatever you have lying around)
-Something metal to heat up and melt the wax (I used a tent peg)
Step 2: Cut the Strip
Fold the long piece over and place matches inside.
You can use the whole striker strip if you want, I didn't because you don't need to. BUT you do need a long enough strip to fold in half over the matches (see pics)
Step 3: Wrap the Match
Once you're done put a drop of wax on the loose end to secure it.
Step 4: Make a Loop and Attach It
-Take a piece of thread (longer than before) and fold it in half
-Twist it many times in one direction
-Fold it in half again and twist it in the other direction
-Repeat a few times until it is a few inches long
Basically I made my own string out of cotton thread.
After that, make another slipknot thread like in step 3 but shorter. Wrap one end of the thicker string so it won't move, then wrap the other end to the other side of the match. Again use a drop of wax to secure the loose end.
Step 5: Soak the Lot
Basically you want to soak the lot in wax, or completely coat the outside to make it waterproof. You also want to cover the wooden parts of the matches to keep water out, as well as any small holes in the bottom of the cardboard wrap. This can be a messy job.
First you need a puddle of wax, so I heated up a tent peg on the stove and stuck it in my wax block to create a puddle to dip the match in.
If you are using a candle, it would be much easier to slowly drip wax onto the match.
Also don't glue the loop together with wax, you need to be able to get a finger in there!
Step 6: Finished! (video)
Now the matches are coated in wax, they won't behave like a normal match. You will have to hold it upside down slightly to start heating up the wax which will then act kind of like a candle so the match will burn longer, hotter and brighter. But if you are not careful, the match can go out quickly if the wax is too thick.
Also, if you did a good job you can push two new matches into the striker to light more matches, or re-coat it in wax again.
That's it, feel free to adapt it however you like for your purpose, and don't play with fire! Also be sure to comment, rate or whatever.
