Freezing of Tapestry

• 1). Roll tapestry so it will fit into the polyethylene bag. Folding may cause permanent creases in the tapestry. Extract as much air as possible and seal the bag with duct tape. Leave the bag with the tapestry inside at room temperature for 4 hours prior to freezing.
  
  
• 2). Place the bag with the tapestry into a chest freezer for 48 hours. Place flat without anything on top of the tapestry. Leave the freezer door shut to maintain a constant temperature.
  
  
• 3). Remove the bag from the freezer after 48 hours and leave the tapestry in the bag at room temperature for 4 hours. Condensation may form, but it will only form on the outside of the bag. Remove the tapestry and inspect it for bugs. Brush or vacuum the tapestry carefully to remove any dead insects or eggs.
  
  
• 4). Repeat exposure may be required. Cycles of warming and then freezing may be required to destroy all insects.
