To begin there are three different recipes that I know of to use for the glue mixture, below you will find all three listed for you, experiment and decover which one works best for you.
Using White Glue
1 cup white glue - like emlers
1 cup water
just mix and dip your newspaper strips into, then let dry.
Using Wallpaper Paste Powder
just add enough water to reach gravy consistency, then dip your newspaper strips into, then let dry.
Using Starch
just dip the newspaper strips directly into the starch, paper mache', then let dry.
NOTE: There is also a recipe for using flour unfortunatly I don't have this one yet.
