• 2 parts Elmer's regular white glue (not school glue)
• 1 part Sta-Flo regular liquid starch

Mix well. Putty must dry a bit before it is workable. It may be necessary to add a bit more glue or starch; you will have to experiment. Some suggest equal parts; others have success with starch to glue 2:1. Recipe may not work on a humid day!
