All of these items should be available from your self storage office. Soft Items like pillows and stuffed toys do well in large plastic garbage bags. Wardrobe boxes are excellent not only for storing clothing, but also for storing draperies and even dining room chairs. You'll want to keep everything else boxed and labeled to protect against dust and for easy access. Plastic drop cloths should never be used to cover wooden furniture.
Dust can get between the plastic and furniture and gradually rub off the furniture finish.
Instead, use old blankets to cover fine furniture. Refrigerators should always be stored upright. Washing machines should be drained and the agitatior stabilized before storage. Wrap electronic items in plenty of packing material such as bubble wrap or wrapping paper. Do not use foam peanuts with computers.
