Things You'll Need
Instructions
Sheath clippings in acid-free or polyester film folders. This will allow the clipping to retain a flat, uniform shape and neutralize any acids in the air or on other papers that they might come in contact with.
Store the folders in a heated room with 35 percent relative humidity and between 60 and 70 degrees Fahrenheit. This should stabilize the clippings and stop them from absorbing moisture or scents.
Keep folders away from sunlight and fluorescent bulbs to avoid fading and yellowing.
