“It’s in the Bag,” Friend, May 1985, 26
You will need 1/4 cup liquid laundry starch, 3 tablespoons powdered tempera paint, large plastic bag that can be tightly sealed, and masking tape.
Put starch and tempera paint into bag and carefully push out air before closing and sealing. Tape top shut as extra precaution to prevent leaks. Squeeze bag gently with fingers to mix.
Place bag on table. Use fingers and hand to create picture. To make different picture, simply smooth out what you’ve done and “draw” again.
