Hay dos tipos principales de papel maché:

Saber cómo preparar la pasta con éxito

1. Prepare the paper: tear up your paper into little pieces (newspaper works well and is free) or collect paper from an office shredder. In some instances, this will be good enough, but if you need finer pulp, throw the paper into a blender with some water.
2. Leave the paper in water at least overnight to soak, or boil in abundant water until the paper dissolves in a pulp.
3. Drain excess water through a fine sieve. Don't plug your sink with pulp.
4. Add adhesive - which could be white glue or wallpaper paste or any of a variety of other adhesives depending on the desired effect. Amounts are not given here - you need to experiment to find a consistency that works well for what you are trying to do.
5. Shape the pulp directly over or inside the a form. You can also sculpt directly like clay without a form to guide you, especially for smaller or simpler objects

Saber cómo preparar el pegamento

The Paper Strip Method uses layers of paper strips glued together with adhesive.

1. Tear or cut your paper (newspaper works well) into strips. The width and length of the strips will depend on the size of the object you want to create.
2. Create a form for support on which to glue the paper strips. It can be an armature or skeleton, often of wire mesh over a structural frame, or you might use an object to create a cast. Oil or grease can be used as a release agent if needed.

1. Make your glue after you are all ready to use it as it will start drying out. The traditional glue is

• 6 cups water
• 1 cup white flour

Mix the flour into the water thoroughly with your hands, being sure to break up all the lumps. You might try heating the mixture too, but do not let it come to a boil. You can vary the amount of flour or water to make the glue thicker or thinner. Experiment to find what works best for you.

You can also add a few tablespoons of bleach to retard the growth of mold, but make sure everyone who is going to use the paste knows that you did this - after all, flour and water are the same ingredients that you use to make bread, and you don't want your Pathfinders performing any taste-tests on a bleach-laden batch of glue!

1. Soaked the paper in the paste until saturated
2. Layer the saturated pieces allow to dry slowly
3. When the glue dries, the paper stays in place and binds together forming a (hopefully) beautiful sculpture.
4. Once dried, the sculpture can be cut, sanded and/or painted. Waterproofing with water-repelling paint works well.

The traditional method of making papier-mâché adhesive is to use a mixture of water and flour or other starch, mixed to the consistency of heavy cream. Other adhesives can be used if thinned to a similar texture, such as polyvinyl acetate-based glues (wood glue or, in the United States, white Elmer's glue). Adding oil of cloves or other additives such as salt or a little bleach to the mixture reduces the chances of the product developing mold.

Here are some thoughts on the paste from Wikipedia: Paper Maché

Paper-mâché paste is the substance that holds the paper together. The traditional method of making paper-mâché paste is to add one part water to one part flour. Some artists prefer to boil the paste, saying that it makes the consistency smoother. Water to flour ratio is changed to five parts water to one part flour in this case. Other artists use a three to one or a one to one ratio of water and Polyvinyl acetate (PVA glue). Still others say that starch makes a fine paste. Adding a dash of cinnamon to the mixture gives the paste a pleasant smell; adding a dash of salt reduces the chances of the product developing mold.

The painting adds the color, while the varnish makes the art more water resistant and gives it a solid surface. Have fun.

As the instructor, you will be responsible for judging the workmanship of the projects. The most important consideration is that you apply a fair standard and not show favoritism. Pathfinders are quickly able to detect unfairness, as it is an extremely important concept to them.
