Start off by tearing the newspaper into tiny pieces and putting them in a large bowl. Add just enough warm to hot water to completely cover the newspaper. Let it soak several hours or overnight.
Once your newspaper has soaked for several hours, get your hands into it. Play with it, mix it, and squeeze it through your fingers until it looks similar to oatmeal. Try to get as many lumps out as possible. If necessary, add a bit more water and let it soak a little longer.
Once you have it as smooth as possible, add a few tablespoons of salt to help retard mold. Mix it again with your hands. Once mixed thoroughly, squeeze out any excess water and add a few tablespoons of glue. Now you are ready to use your paper mache pulp!
If you don't want to wait overnight, you can add your newspaper to boiling water and let it boil until the newspaper falls apart. You have to watch this carefully and possibly add extra water if necessary. You can also try letting your newspaper and hot water mixture sit for a few hours and then put it in a blender or food processor. Don't forget to add the glue and salt once your mixture is smooth!
Tip from Anna: "I used your method to boil newspaper pieces in boiling water in order to make paper mache pulp. The method worked. However, the pot that I used was smeared in newspaper ink on the sides. I tried soap, baking soda, vinegar and finally came upon a solution that quickly removed the ink: vegetable oil. I used the oil and a paper towel & was able to quickly remove the residue in the pot. I thought it would be helpful to include this remedy in your article for those of us who end up with dirty pots."
Store your pulp in an air tight baggie or bowl in the refrigerator for several days!
