You know those tiny little balls of fabric that collect on the sleeves of your favorite sweaters? You hate them, don't you? Well, you can save your sweaters from looking worn-out with a ever-so-clever sweater stone. By gently rubbing the sweater stone along the surface of your knits, you can gently remove the offending pills without damaging the fabric. The natural, pumice-like material of the sweater stone is perfect for delicate fabrics like cashmere, but it's also hearty enough to handle heavy upholstery and blankets. I first became a believer in the pumice stone when I lived in the Netherlands. Having tried everything from a safety razor to those electric sweater shavers, I can say with confidence that the all-natural sweater stone is the best depiller around.
