This is the before shot...I used Wilton Icing paste in the brown color. I previously soaked my wool in a vinegar bath for about an hour and squeezed out as much water as I could. I set it aside and then I added the dye to a pot of vinegar water. I didn't measure, but if I had to guess I probably used 4 cups of water and 2-3 tablespoons of vinegar. I then put the wool into the pot and turned the heat to simmer. I let it sit in the warm bath until the water was clear. This took about an hour. I slowly pulled it out so I didn't burn myself or agitate the wool and really didn't like to color. It was still pink just a bit darker, like a dusty rose shade. So I pulled out more of my food colors.
Here's the wool in the brown Wilton bath.
These are the additional colors I used. After pulling the wool out and setting it aside I added about 12 drops of blue and about 4 of yellow. I swirled it to mix and returned the wool to the pot. It remained on simmer for about another hour until the water was clear(ish). I gently pulled it out and rinsed it in cool water.
And here is my new dyed wool. I put a piece of the 'before' color on it as a comparison. It is a brownish rust color...very earthy. It was super easy and fun to over-dye wool so I'll probably do it again. It was just time consuming.
