It seems strange that it took me so long to consider a tool to care for my wool sweaters as they are a somewhat daily uniform during Seattle winters. But just this year on a whim I bought a sweater comb from The Laundress. And now I wonder how I ever got along without it.
Along with my OXO sweater racks and Eucalan wash, this little tool has been a lifesaver and works beautifully to remove all those unsightly little balls keeping my sweaters, scarves and delicate knits in good shape. From the Laundress blog, "pilling is a direct result of wearing. When fibers become loose, they form little balls, which are commonly found on loosely woven woolens, knitted synthetics and blends."
I just ordered the Sweater Stone which is specifically for heavier wools like outerwear, thick sweaters and even upholstery and blankets.
