Hooking along on my Vogue rug I had begun to use a hank of wool I had dyed back in the ice age when I was teaching myself to dye yarn. This teaching consists of making a kajillion mistakes and continuing to soldier on.
I like to use the electric frying pan for this.
Make sure your wool is arranged in skein and is loosely tied in four points. Wet it.
Make three to six colours of dye in jars, use 1/2 cup of water, more if you skein is big, or thick wool.
Lay your wool in the frying pan, try to get it as much of it in contact with the bottom of the pan as you can. DO NOT ADD WATER.
Turn on your pan.
Pour the first colour over the wool in a cross. Wait for this colour to mostly take up
Pour the next colour in a cross beside the first cross.
Work in this pattern adding all colours one at a time. DO NOT STIR. You can flip over if you wish to inspect for undyed parts and redo them using the colour in that area
Heat until all colour is gone from the dye bath.
