I generally dye my weft yarns for weaving twice a year: in the Spring when all the snow has melted from the back yard and in the Fall when the leaves are turning the same color as my favorite golden yellow weft yarns shown above!
I dye a total of 16 ozs (1 pound) of wool per dye bath, so in the big bread bowl above, I gently washed and rinsed 8 2-oz skeins of yarn. After your wash and rinse, let yarn soak in the bowl for another hour before placing in dye bath – this allowance of time gives your yarns better absorbtion of color as well as evenly-distributed color.
I ALWAYS DYE OUTSIDE. It is safer, especially if there is no wind. I use Lanaset commercial dyes for my weft yarns; they are color-fast, intense colors that will not fade easily. Follow the directions in your Lanaset dye recipe. Make your dye bath accordingly. Always wear rubber gloves when working with commercial dyes; always wear a dust mask too especially if there is wind or in an enclosed space – commercial powder dyes are toxic!
