Begin by wrapping a strand of yarn around yourfingers several times. Slip your fingers out and wrap the yarn around thisfirst bunch. Continue to wind yarn into a ball, crisscrossing to keep it round.Wind snuggly.

Once you have wound your ball (approximately half of a 100 gram skein), tuck the end in tightly under several layers. Place the balls of yarn into one leg of the nylons. Tie of the end so the ball is securely encased in the nylons. You can do multiple balls of yarn at a time in one leg.  

Wash the nylon encased balls on the hottest setting on your washing machine. Dry on the hottest setting. Do this 4 or 5times, going from hot washer cycle to dryer. The heat will make the wool felt and instead of a ball of yarn, you will have a ball of wool.

I did the last two dry cycles with clean towels to make sure all moisture was removed.

Once the balls are fully felted, you can use these in your dryer to speed up drying time and to fluff towels. You can add a few drops of essential oils if desired.
