YOu can get 100% unbleached natural tampons from health food shops. Most tampons are a mixture of cotton and rayon. I havent tried them but I was considering it due to their handy shape and applicator to shove them back in once charred. I made some Charred cattail head, my first batch so Ive not much to compare it to. It takes a spark from a magnesium fire striker, but I dont know about flint and steel. Ill bring the tin along to the bushmoot, people can try it if they like. ANyway, Id rather try something else as the cat tail is far to flimsy, you have to bundle it up or else it blows away and then your fingers are sooty.
