Pilling is a vexing cold-weather wardrobe issue that’s difficult to avoid altogether; however, there are ways to keep sweaters from appearing ragged due to yarn clumps known as pills. They form when yarn fibers in a garment become damaged or loose; when the ends of the fibers are exposed, they get tangled up. The internet is cluttered with ways to remove pills using products you might already have at home, like a disposable razor or sheet of sandpaper, but we’ve found that a fabric comb with steel mesh is very effective at scraping away the clumps and recommend it over anything else that’s not designed to remove pills, to avoid any mishaps. There are also pumice stones and electric shavers that sit at comparable price points with thousands of positive reviews on Amazon, though some experts say the latter damages the halo, or the yarn’s fluffiness, in the long run.
