1) Technic #1 (easiest):
Fold (dry) the model as far as possible. When the folds become too difficult, wet the flaps and creases with a damp sponge or water spray.
2) Technic #2:
Moisten the entire sheet with a damp sponge or a water spray. Fold your model quickly before it dries. Dry with a hair dryer or outdoors holding sometimes parts of the model with clothespins.
