Most items shouldn't need to be washed, but if it ever comes up:
Items made with acrylic yarn can be put in the washer on a delicate cycle, but the water should not exceed a temperature of 104°F/40°C. It can be put in the dryer on low heat (although we recommend letting it air dry instead), but cannot be ironed or bleached.
Items made with cotton yarn (mini dishcloths, for example) can be put in the washer on a delicate cycle not exceeding 80°F/30°C. It can be put in the dryer on a delicate cycle with low heat, but cannot be ironed, bleached, or dry cleaned.
