This was our first go.
As far as I can tell, it turned out alright.
The roving still seems fit to be spun (on our homemade drop spindle).
Here's how we played.
Everything I read said to start with an ounce of wool.
We put the wool into very warm water and let it sit for twenty minutes. For the blue, I just used a couple dozen drops of food coloring and some vinegar (1/2 cup or so?)...
I stirred the coloring and vinegar into the water pot,
we placed in the wool,
we set it on the stove on a medium-low temp, made sure it didn't boil (I read it could felt the wool if it boiled) and we let the wool soak up the coloring.
It took about twenty minutes before the water was clear (the wool soaks up the dye).
We put it in a warm (not hot) bath to cool it, then set it on towels and hung it to dry.
For Madeleine's and Trevelyn's wool, we used koolaid. Grape and lemon-lime.
We dissolved the koolaid in water, and after the wool had soaked in the warm bath for twenty minutes, we set it in the dye bath.
We put it on the stove top just as we did the food coloring, on low-medium heat for twenty minutes. (I read that you can take it in and out of the microwave every two minutes, but we don't have one, so.....)
We rinsed and finished as we did the others.
The next one I did was a koolaid and black cherry tea mixture. I love the color! It's the plumish rose color.
Another one I did just with the tea.
It's very light, but it's very pretty.
The last one I wanted a tri-colored yarn, so in a pie plate I spiraled the roving, and striped it with the tea, the blue vinegar mixture, and the purple koolaid.
Since I couldn't stove top it with out mixing up the colors, I placed it in the oven at about 380 for probably 35 minutes total.
I added more dying liquid a couple of times to darken the dyes and to make sure the wool wasn't drying.
It turned out beautifully!
No doubt professionals would gasp and sputter at our measures, as I am sure we didn't do it perfectly, but we need some lovely yarn for a project we'll be working on for Earth Scouts.
I'm very pleased with our colors, and can't wait to spin it for weaving.
