1 cup white school glue
3/4 cup liquid starch

Directions:

Pour the glue into a plastic container and then add the starch. Stir the ingredients and knead the mixture with your hands. If it sticks to your hands, wipe a little starch on them. If the ingredients don't seem to be mixing well, you may need to heat them in the microwave (heat long enough for them to mix). Allow the mixture to set for a while and store it in a closed container in the refrigerator.
