Glue for papier mache

 Posting this so I don't lose the recipe!

To make papier mache paste with cornstarch and boiling water:

Boil 3 cups of water in a medium pot
In a small bowl, whisk together 1/2 cup of cornstarch and 1/2 cup of cold water until smooth
While the water is boiling, slowly pour the cornstarch mixture into the boiling water while whisking
Turn off the heat and continue whisking until the paste thickens. Let the paste cool

The boiling water helps cook the paste, making it stickier and longer lasting. You can store the paste in an airtight container and use it within a week.
