What's in the dye pots?

Weighing out one ounce increments of Romney wool roving in a light gray.  Then I tie them with cotton.  I add two to each crock pot to dye.

They soak in a water bath with a couple splashes of vinegar for 20 minutes.  I can then prepare the dye solution. 

Then I add dye.  This time three colors.  A blue, light green and teal.  I turn on the crockpot on high.  I let it sit covered until heat set or starting to steam.  I turn off the crockpot and I leave alone until cool.  Rinse and let dry.  

The top once was my first attempt.  No natural color remained and a bit dark.  The second a bit too light.  Similar with the third.  Getting closer though.  One spun into a two ply it looks like this:

  I have washed and hung to dry.  I hope to start the sweater spin soon.  Ended up with a Dk weight.  Now off to pick a pattern.
