Felting wool in a washing machine. Adding soap is not completely necessary but ideally youd use soap for washing delicates. You have never done any felting. Most yarns that are 100 wool will felt to some extent with the exception of super wash varieties.
Machine felting is a great and easy way to create unique felted objects simply in your washing machine. Once the machine starts churning start checking the progress every few minutes. Add 2 tablespoons of liquid dish soap to the water and then throw in the pillowcase with a few pairs of jeans.
