I took a section of pant leg, white/off white thrift store pants, and put it in a bowl with warm water and dissolved Kool-Aid. Stirred, Microwaved 2 minutes, stirred, set 5 minutes, stirred, microwaved 2 minutes, stirred. By now there is no color left in the water. I left it in the water to cool, then rinsed and let dry. then ironed. I should have spent .40 and doubled the dye. However I'm not real happy with the color of orange.
I got some acid dye for wool and will try again.
