Instructions:
Make sure you cover you work surface well. I usually set down newspaper first and then wax paper or plastic wrap on top of the newspaper. This is a very messy project!
Decide what size and shape of mask or head you want and choose the appropriate sized balloon. Blow up the balloon and tie it closed. Find a bowl or cup your balloon can sit in while you work on it. Completely cover the cup or bowl with plastic wrap so the paper mache does not stick to it. Also cover the table or work surface under the cup with the plastic wrap. Set your balloon in the cup or bowl and set it aside.
Tear several newspaper pages into strips. You will want them 1 inch wide and about 6 - 8 inches long. Set them aside.
Use a large bowl to prepare your paper mache paste (Pick a recipe here). The paste will be sticky! I would suggest using a bowl that is easy to soak and clean (glass perhaps) or even a disposable bowl. Now you are ready to start with the paper mache!
Dip the newspaper strips into the glue and spread them onto the balloon. Completely cover the balloon, except for the area where it is sitting in the cup. Set aside and let this first layer dry.
Once the first layer is completely dry, use various supplies to make the facial features on your ballooen if desired. You can make a nose, ears, thick eye brows, lips, etc. Use cardboard, masking tape, foil, or other items shown on this supply list. Use masking tape to hold everything in place.
Add atleast two more layers of paper mache to your balloon. Allow each layer to dry completely before putting on the next layer. Once it is dry, pop the balloon and remove it through the opening left at the bottom (If you cannot get the balloon out, don't worry about it too much - No one will see it).
You can now paint and decorate your mask or face as desired. You can add hair using yarn, thin scraps of material, or anything else you desire.
To make a more realistic shaped face, make as above except use a double layer of tin foil instead of a balloon. Use your face as a mold. Have someone help you gently press the tin foil to your face to get a nice face mold. Wad up newspaper and put it inside the curved section of the foil mold and lay it on your work surface. While applying the first layer of newspaper and paste, make sure not to press on your mold too hard or it will lose it shapes!
