  • Crochet hook

  • Old pantyhose

Make wool dryer balls with a sweater that is at least 80% natural fiber.

With the mantra "reduce, reuse, recycle" on everyone's mind, reusing an old sweater by recycling it into wool dryer balls will reduce the need to purchase dryer sheets. With old sweaters lying around, there is no need to purchase new wool for this project. Use an adult-sized large sweater to make at least three wool dryer balls from one sweater.


Step 1

A sweater that is too small, big or full of moth holes is perfect for this project.

Lay out the clean and dry sweater on a flat surface. Cut a 3-inch square out of one layer of the sweater.

Step 2

Ball up the square in your hand, pressing it as tightly together as you can. Wrap a scrap of yarn around the ball at least 10 times. Secure the end by tying or pulling through the ball using the crochet hook. The square should remain in a ball after cycling through the washing machine. Wrap it with more yarn if you feel it is needed to stay secure.


Step 3

Putting the sweater ball into pantyhose avoids clogging your washing machine.

Place the sweater ball into the leg of an old pair of pantyhose, and tie a knot in the pantyhose to secure the sweater ball. Cut off the excess pantyhose.

Step 4

Set the washing machine on hot, and run the sweater ball through an entire wash cycle. Remove from the washing machine, and run through the dryer for a complete cycle. Remove from the dryer.


Step 5

Remove the sweater ball from the peg of the pantyhose. It should have started to felt. When it is properly felted, you will not be able to see the individual crochet or knitted stitches in the sweater ball. It will look very similar to a piece of felt you purchase from a store. You can repeat Steps 3 and 4 again if you prefer it more felted.

Step 6

Cut a 7-inch square out of a single layer of the sweater. Wrap the square around the felted ball. Secure by wrapping with the yarn scraps again, and secure the end by tying or pulling through the felted ball with the crochet hook. Repeat Steps 3, 4 and 5. If you are satisfied with the size of the wool dryer ball, you are finished. If not, go to Step 7.


Step 7

Cut an 11-inch square out of a single layer of the sweater if you prefer a bigger wool dryer ball. Wrap the square around the felted ball, and secure by wrapping with the yarn scraps. Secure the end by tying or pulling through the felted ball with the crochet hook. Repeat Steps 3, 4 and 5.


These balls will felt every time they are used in the dryer, so it is OK if they are not completely felted when you are finished.

You can also put a small sachet of herbs inside the first ball to scent your clothes. Once the smell wears off, there is no way to replace the sachet.
