Giving them proper storage is like providing them a proper place to sleep.
Giving your bags proper storage is like providing them a proper place to rest. When they are not in use, it is important to keep them well in a cool, dry area away from extreme heat and temperature. But before anything else, make sure each piece is dry. Cover each in dust cloth before putting in shelves or boxes to keep them from dust and moist. If you are planning to display them in shelves, make sure to fill the inside with crumpled papers to maintain its shape. Hanging them can also wear them out so this technique should be out of your options.
