<human>:  What is the best way to properly store a wool sweater?
<bot>: The best way to properly store a wool sweater is to fold it and place it into an airtight container or a sealed plastic bag. This will help prevent moths, dirt, and dust from coming into contact with the wool fabric. It is also important to ensure the container or bag is moisture-proof, as wetness can cause wool to become discolored or generate lumps. Additionally, make sure to store the sweater away from direct sunlight, as it can fade the fabric.
