Using a question and answer format the author illustrates general guide lines that deal with the basic principles of period costume care. Some aspects of the care and handling of costumes are: the factors that affect the fragility of garments; the frequency of handling; special works areas; the use of plastic sheeting; methods of storage; techniques for handling; sources of information on cleaning and restoring; labeling and harmful environmental elements. Every costume must be considered individually, since each has its own unique problems depending on its composition and the elements to which it has been exposed. -- AATA
