Sometimes even the nicest wools and cashmere may pill where there is friction on the garment (like the underarms or shoulders). Pills are the little balls of fibre that start to gather on your sweater and can make the garment look shabby if not removed. These annoying little balls of fibre can be quickly taken care of with a small hand-held electric de-fuzzer, a sweater stone, or if you’re feeling super patient, by picking them off. This keeps your sweater looking fresh and new.
