As Alpaca is a naturally occurring yarn some pilling will occur over a certain period of wear. Using a wool comb, razor or fabric shaver will help you care for your Cayo piece. Softly glide the wool comb or razor over the affected area to remove the pills. Use long strokes to avoid pulling any yarn. You can also remove the pills simply by pulling them off. We recommend that you wash your CAYO sweater after a couple of wears. You will need to continue to remove pills until the pills no longer occur.
