Tea bag firelighters .
After my experiments with cardboard toilet roll tubes soaked in wax https://ru-titley-knives.tumblr.com/post/172278039861/bog-roll-fire-lighters-a-great-way-to-recycle
My Dad suggested I try tea bags too which he had been making at home , it was only after he showed me his when he came to stay that I discovered it had been done before and was all over You tube , naturally he was quite sad about this .
Simply dry out your bags after use and soak in waste candle wax warmed in a pan then remove and allow to dry .
Ive found that real tea rather than herbal work best I drink Punjana and Earl Gray so have used these .Results have been pretty good with bags lasting as long as 7 minutes and are really easy to light even after a proper soaking in water to check if waterproof .
