Registration is closed
Workshop details:
Learn how to safely flatten rolled or folded collection materials so they can be more easily accessed and handled through use of three simple humidification and flattening techniques.  The use of gentle humidification allows paper fibers to relax so they can be safely unrolled and manipulated to remove folds and creases.  Flattening occurs when the humidified object is dried under tension or restraint. 

The drying technique presented in this workshop is one that is frequently used by conservators and preservation professionals and requires minimal setup.
