A simple guide to carding wool for knitting or art
PDF download Download Article

Wool carding involves separating and straightening sheep’s wool with two brushes so that it can be used to make fiber art or yarn for knitting. These brushes closely resemble pet hair brushes but are made specifically for preparing wool fibers. Carding can also be used to create various fiber blends or combine different colors. Once you are familiar with the process, you can begin hand processing wool at home.

The Best Way to Card Wool

Soak the wool in warm water and dish soap for 10 minutes. Rinse out the soap and let the wool dry. Then, add a thin layer of wool onto a hand carder. Take another carder and brush it over the wool. Keep brushing until the wool transfers to the other carder.

Washing the Wool

  1. You will want to card only clean wool, as any dirt particles could hamper your ability to use the wool carders. Freshly shorn sheep’s wool will also have dirt deep in the fibers, so you will need to be sure you wash it thoroughly.
  2. Grab a bucket or clean out a sink to use as a washing basin. The basin should be large enough to comfortably contain the amount of wool you would like to clean. The temperature should be at approximately 180 degrees Fahrenheit (82 Celsius). Water that is too hot will strip the wool of natural oils.

  3. To protect the woolen fibers, avoid soap or detergents that contain bleach or similar whitening additives. Stir the detergent into the water until the water is soapy. [1]
    • For best results, use a soap or detergent with a pH between 7 and 9.
    • Most mild dish soaps are neutral (a pH of 7) and should be safe to use for cleaning wool. [2]
    • Mild dish soaps can be purchased at any drug or grocery store near you.
  4. Let the wool soak for about ten minutes in the basin of warm water. This should loosen the dirt particles, making it easier for the dirt to separate from the wool or for you to remove it with some light scrubbing. Rub the wool with your hands to wash it thoroughly. [3]
    • Repeat the process as necessary. You may need to soak the wool 2-3 times before it is completely clean.
  5. Remove the wool and pull the stopper to allow your sink to drain or dump the water out of your bucket. Rinse out any remaining dirt in your sink or bucket.
  6. You will know it has been thoroughly rinsed when you notice that the bubbles from the detergent are gone. You may need to rinse the wool three or more times.
  7. This will absorb the excess water in the wool, allowing it to dry a bit faster. Wrap it in the towel and gently squeeze to pull out as much excess moisture as possible. [4]
  8. You can do this by clearing a space on a desk or countertop and laying the wool on another clean and dry towel. You could also lay it flat on a drying rack. Allow the wool to dry overnight. Do not attempt to card the wool until it is completely dry.

Hand-Carding Wool

  1. Carders are wooden paddles covered in pin board and they often closely resemble cat or dog hair brushes. Be sure to avoid purchasing carders made for cotton and purchase ones specifically made for wool.
    • Wool carders come in small and large sizes. Larger sizes can be harder to manage if you have little upper body strength.
    • Some wool carders have teeth that are very close together. They are harder to drag apart but align the wool into finer wool.
    • Hand carders have different types of teeth as well, which are used for different purposes. Carders with coarse teeth are used for carding coarse fibers, such as wool and mohair. Hand carders with fine teeth are generally used for carding softer fibers like cotton and angora.
  2. The wool should be touching the side of the carder with the pin board. You will want to cover it the surface of the carder until almost all the teeth are covered but not so there is an excess of wool hanging off the side of the carder. Do not cover other carder with wool.
  3. Place the full carder on the on your left knee with the wool facing up. Hold the handle of this carder with your left hand. Switch hands and knee if your left hand is your dominant hand.
  4. The carder should be oriented so that the pin paper is facing down and toward the wool on the other carder.
  5. Begin at the top end of the full carder (opposite the handle). Work your way gently from the top to the bottom in full strokes moving in one direction. There is no need to press very hard. The pin paper should grab a few fibers at a time, straightening it onto the second carder. [5]
  6. If you see any knots, continue brushing until they are removed and transferred onto the surface of the other carder. This could take up to five minutes to complete, depending on how fast or slow you prefer to go.

  1. Transfer the now-full carder to the left knee. Take the empty carder into your right hand. Gently brush the empty carder over top the full one, as you did previously.
  2. You will continue to switch your carders until no dirt appears and the wool is very uniform. Look closely at the brushed fibers. If they are falling in parallel lines, then it is ready.
  3. Start at the top of the carder and slowly move to the handle, lifting the wool the whole way. You can use the other carder to help lift the top of the fibers up and back. As you lift, you can gently and loosely roll the wool until it resembles a burrito. Once the fiber is rolled, it is referred to as a rolag. [6]

    I washed my wool in the washing machine and it matted badly. How can I untangle the badly matted felt so that I can still make wool roving out of it?
    Community Answer
    When this happens, it is known as "felting" the wool. This happens as a result of the agitation in the washing machine and there is usually nothing that can be done except use it in a different project, such as a felted bowl, purse, or blanket.
  • Question
    I don’t have a carder. Is there anything I can improvise one out of, or do I just have to go get one?

    You can use two dog brushes. That works just as well. You could also try human brushes, but they might not work as well.

      About This Article

      Article Summary X

      Before carding your own wool at home, purchase a set of hand carders from your local spinning or hobby store. Then, wash the wool in a solution of warm water and mild dish soap to remove the dirt and let it dry by laying it flat on a thick towel. Next, cover the pin board of 1 of your carders with the freshly washed wool, then brush the empty carder over the top and keep brushing until all the wool is transferred to the other carder. Switch carders and repeat the brushing process, and continue to switch carders until all the wool falls in parallel lines.
