I like to use and make dryer balls because they are eco-friendly. They can be reused over and over again unlike dryer sheets and they are not made of chemicals like the dryer balls made of plastic. I run my dryer for less time now, because the super absorbent wool dryer balls pull the moisture out of my clothes and dry up faster than the material around them.
Dryer balls can also be scented by adding one or two drops of essential oil to the surface, then letting sit for 10-15 minutes to allow the oil to absorb. The dryer balls will give your clothes a lovely smell for up to a month without having to be re-scented.
Using only two dryer balls will help with static, but the more you use, the shorter your drying time will be.
