Cover the top of the gown with cotton fabric before closing the box. Fold the cotton fabric along the long sides first and end with the narrow sides. Use these narrow ends to pick up the garment when removing it from the box. This cotton sling serves to reduce the amount of tension on the garment when handling occurs. Do not use plastic bags inside the box.
Plastics are chemically unstable and trap moisture, allowing mold and mildew to grow.
If you suspect leakage in the storage area, place a loose covering of plastic sheeting above the box that will still allow sufficient ventilation. Refrain from depositing the box directly on the floor. Boxes should not be sealed. Fabrics are frequently made out of organic materials which require air circulation. Some boxes have slits that allow air to circulate but this is not necessary.
