Here are some simple ways to solve the problems of dampness. Tie a dozen pieces of chalk together with string or use a nylon mesh bag such as the type that onions come in to hang in closet. If closet already has a musty smell, use a bowl or an old nylon stocking/leg of panty hose, or small gauze bag and hang up filled with cedar chips or lavender to refresh. Don’t stuff closets too full, leave some space for air to circulate. When you use the  dehumidifier, leave the closet/cupboard doors open and run to absorb the excess moisture.
