Storage areas should be clean, cool, dry, dark, and free from drastic changes in temperature. Textiles should be cleaned and stored un-ironed and un-starched. There should be no contact with tissue or paper. Paper tends to be acidic; acid is especially damaging to textiles. Instead, wrap textiles in clean, white cotton or muslin cloth. Textile fibers need to be in an environment where there is some air movement; the best place to store antique textiles is on top in a drawer.Textiles also should not be exposed to light because the natural cellulose fibers (cotton and linen) and animal fibers (silk and wool), of which most antique textiles are made, are damaged by the sun and indoor light fixtures. The ideal temperature is 65-70°F (18-21°C), with relative humidity between 40% and 50%.
