This item lived up to its promises! I wanted to make felted wool dryer balls. They felted on the first go round. I just wound them into balls, tucked the end in, knotted them tightly in a nylon, washed on the second hottest setting, and then dried on the hottest setting. They are making a HUGE difference in the drying times and all of my clothes come out dry every time now. Even the loads of towels and jeans. And as an added bonus, these were the cheapest skeins I found! Thanks!
