Discharging Natural Dyed Fabrics

I will be posting instrutions, I've gotta find the videos first, on how to discharge natural dyed fabrics on the network, so far I've added a few blurbs for some simple discharge techniques.  The question was how to discharge madder dyed silk fabric using the silkscreen method... and I made a video about six years ago on this very topic.  

If nothing else this is an excellent reason for me to break out the dyepots this week and dye up some fabric!
