As your sweaters and other cold-weather items go into hibernation for the summer, use this trick to make sure they stay odor- and moth-free. Cotton muslin bags, commonly used to mull spices, can be used to make sachets. Fill a bag with fragrant dry ingredients, such as thyme, cloves, lavender, mint, or cedar, which are all thought to be natural moth repellents. Tie the bags shut, and pop them in closets and dresser drawers. Next fall, you'll smell the sweetness of wardrobe-keeping success.
