A simple paper mache recipe would be to mix 1 part flour to 2 parts water. In other words, if you are using 1 cup flour, you would mix with 2 cups water. It should be about as thick as glue. Mix well to make certain there are not any lumps. To prevent mold, you may add a tablespoon or two of salt to the mixture and dash of cinnamon or vanilla adds a nice scent.
