We have started making wool Dryer Balls, they are very popular with the Farmers Market crowd. 3 balls used in the dryer reduces drying time by 1/3 to 1/2 depending on your dryer. They work by absorbing moisture and increasing air circulation and rotation.  They also reduce wrinkles! They work  especially well with natural fibres like cotton and are a safe for sensitive skin, so great for cloth diapers. The  David Suzuki Foundation has given these energy efficient little guys their stamp of approval!  You can even add a few drops of essential oil to the surface to add your own natural fresh scent to your load.  We sell them 3 for $18. (with or without happy faces).
