came across this idea when i was messing about with some birchbark. They make excellent firelighters for their size/burn time ratio and could with a bit of ingenuity be primed to take a spark.
Start with some bark and rip it into 1cm ish wide pieces.
then rip them carefully into 0.5 cm strips. You need four of them.
fold the pieces exactly in half and with the loop made in one of them, insert the tails of the other
do this with another...
and finally the fourth and you will have a square. in theory!
Pull it in tight.
now this part is the middle and on either side you must tie four strand crown knots. Sounds complex but really all you must do is loop and trap each of the four strands under the adjacent one. Perhaps researching the knot may help at this point if you are stuck.
Three strands folded over...
top half complete.
and the other side.
here is a size comparison to a bahco folding saw blade.
and a whole load of them whic took about 1/2 hour to make
and the most important part - it burning
some of the tightly woven ones have lasted a long time with aconsistent flame and are excellent as firestarter after igniting something with afire steel. You probably could weave it a dfferent way, but this is quite simple.
Have fun,
