I am judging this experiment a modest success. There was some bleed-through, probably where I'd not applied enough wax resist, and the cheapass Rit dye didn't "take" very well, but otherwise the method worked basically the way I wanted. next experiments will be with different dyeing methods (I have some gentian violet that I intend to try using) and also I want to see if liquid waxes (for floors or cars or whatnot) could be used directly to make the wax-resist mask.
