Gather your ingredients. Cook over medium heat. Let your glue cool before using it.
You will use flour, sugar, water and vinegar to make paper mache glue. You can adjust the recipe as needed to make more or less glue. The basic proportions are 3:1 for the flour:sugar mixture. Use one teaspoon of vinegar for every cup of flour you use. If you want a smoother paste, you can sift the flour before you make your paste. Pour your mixture in your saucepan and turn on the heat. Stir the mixture constantly until the mixture begins to thicken. Once your mixture starts to boil, you can turn off the heat. When the mixture has cooled, use it for any craft projects including paper mache. Once you have finished, keep any unused glue in a tightly-sealed container in the refrigerator. This glue will keep for 2 to 4 weeks in the refrigerator.
