Yesterday, I decided to experiment with using McCormick dyes and the crock pot for dying. I soaked my 4oz of Cormo wool for about an hour in the crock pot before beginning.
The three colors I used are Sunset Orange, pure yellow, and Dusky Pink, all drawn from the back of the McCormick box. I poured the dye (3x the icing amount listed on the back mixed with 3/4 cup boiling water and 2 tbsps of lemon juice) over sections of the wool in the pot, which was full of water, then put the crock pot on high. I let the dye soak for two hours on high, and it was completely exhausted.
Here's the fiber washing in the sink post-crockpot:
And drying in the sun on my deck (yes, that baby gate makes a fantastic rack for hanging fiber):
