The Lesbian Avengers handbook is great. The tools are simple. Straighten out wire hangers and wrap one end with cotton string.
Less string makes smaller flames, suitable for beginners.
Really important that no loose string ends are hanging around. Tie them off in knots and tuck the loose bits under. Just make sure each time that no string ends have unraveled. There might be another substance that some Avengers somewhere use, and if you hear of anything else that works well, please let us know. Torches can be stored together with the string ends in a plastic bag until next time.
