Create an armature. Make a large ball of newspaper, bigger than normal-sized head. Make smaller wads of newspaper. Use masking tape to attach these to the large ball for ears, nose, jaw and other desired features.
Cover the armature with masking tape. Fill in any holes around it with strips of paper.
Dip strips of newspaper into paste and apply to the armature, overlapping the strips as you proceed. Work quickly and make the strips as smooth as possible.
Place dry strips of newspaper all over the wet strips. The dry strip will absorb some the paste from the layer of newspaper below.
Dip strips of brown craft paper into the paste and apply all over the newspaper layer. Follow with dry strips of brown craft paper.
Wait for the mask to dry completely. When the mask is dry, remove the newspaper armature from within. You may need to use an X-ACTO knife to remove the masking tape.
Put the mask on to determine appropriate spots for the eyes and mouth. Mark these spots with a pen. Take the mask off and cut out the eyes and mouth.
Finish the mask. You can paint the mask or apply colored tissue dipped in paste. You can also use items like yarn, raffia and feathers for the hair or beard.
