There's no need to purchase expensive store-bought adhesives if you're just pasting paper or other lightweight objects back together. With a little flour and water, you can whip up your own sticky concoction and save your money.
Combine whole wheat flour and very cold water in a saucepan.
Mix the paste with a spoon until it is smooth and free of lumps.
Heat the mixture on the stove until boiling, stirring continuously to prevent scalding.
Cool the mixture on the counter until it is room temperature, or place it in the refrigerator for a few minutes.
Stir the paste until it is soft and use it right away.
Add water to hardened paste to use again.
Be sure to wait until the boiled paste has completely cooled before using it, as the mix is very sticky and hot and might scald your skin.
