So, I bought a Lutz and Patmos sweater designed by Kirsten Dunst from Capitol (clothing boutique) this past summer and I LOVE it. There was one problem, the sweater sheds and knots like crazy, (that's part of it's look, you know Kirsten Dunst has this sort of fabulously grunge look?) Well, I am not sure how I got here, but I picked up an unopened pumice stone from under my bathroom sink and began to bush my sweater with it. Voila! Knots gone! It is a great sweater shaver, and now I carry it in my stylist's kit.
