Rat: I just let mine dry enough that the husk darkens and can be removed by rolling between a couple of sections of newspaper with feet, board, whatever. Put two ort hree cups of husk in a coffee can and add enough water to stir, then let it simmer on a camp stove or hotplate for a few hours. Pour off the liquid and that's your dye. Without adding alcohol, mine would form a head of mold several times during the winter, but underneath it was good dye.
