I am using my Cushings Acid dyes and some superwash wool.
First I wet down the fiber in water with a bit of dish detergent in it. While it was soaking(about 30 min) I made up the dye bath.
I heated some water and vinegar to about a simmer and then added Cushings Acid Dyes in Nile Green.
I put the wet wool into the jar and then added the dyebath.
I set it out in the sun. I thought this might help it take like sun tea. However remembering that these are acid dyes and not natural dyes I might be better to process them in a water bath canner. I might try that today and see what happens.
