Always air the garment after wearing, leave for a 'rest' period and store flat. Handwash in cold to lukewarm water. Use cashmere shampoo or a small amount of household soap. Wash in cold to lukewarm water, rinse, carefully press out excess water (or spin on a short program), dry flat and steam iron through a pressing cloth.
Pilling is a natural process which occurs in all natural yarns after a certain period of wear. Pilling is caused by abrasive stress during wear, or by static electricity build-up underneath outer garments. The protruding ﬁber ends become knotted together and form so called 'pills'. These can either be picked off, or ideally shaved away using a wool razor. Soft, higher-grade yarns are more susceptible to pilling than rustic-type materials.
