I card the wool for two reasons. One is to make blended colors. I dyed the wool in three colors so I could blend them on the drum carder to make color variations for the backgrounds. The second reason is during the dyeing process some of the wool lightly felted on the edges. I'll card the wool to separate these strands.
This drum carder is one of my most favorite pieces of equipment. It was given to me by a friend who was downsizing her studio. Thank you L.! Imagine combining these wools with hand carders. No way.
I am using red, orange, and peach wool for this sample. Add the wools to the feeder and start cranking the handle. Pull the combined wool off the roller. It usually takes at least three rolls to get the color I want.
Look at all that wool. I love the colors I am getting by mixing the blues and other colors. To keep the blended colors separate, I stack them on many large sheets of paper.
