It’s a Sweater Stone! I ordered one for free (ok, $4.99 shipping) and it’s revived a whole closet of sweaters I had put to rest due to pilling.
By the way, pilling tends to happen most in acrylic, wool merino, and cashmere fabrics, all textures I 
love and, thanks to the Sweater Stone, that will be able to keep me warm (without provoking my tendency to compulsively pill-pick) for many winters to come!
It’s simple – just gently sweep your stone (it’s very lightweight, like a pumice) across the entire garment without applying too much pressure (or you’ll stone your sweater into oblivion) – then use a lint roller to collect all the loose pills. That’s it! Your sweater (many of mine are several years old) is instantly chic again.
Also, a very cool message from Gale, the Sweater Stone rep I emailed with:
So I Reduce dry cleaning (chemicals), Reuse perfectly good sweaters instead of throwing them out/buying new ones, and the paper is Recycled? My whole life, I’ve been waiting for this opportunity – the 3 R’s in one step! You’re great, Sweater Stone.
