Fill up your sink (or bathtub if you want to wash a few pieces at once) with warm water and add the shampoo. Gently wash then rinse, but DO NOT wring out! The only downfall to hand washing is that there's a chance it may change the shape of the sweater. So carefully roll it in a towel to remove excess water and LFTD (Lay Flat To Dry). You may need to gently reshape your sweater (called blocking) to make sure it dries in its original shape.
