Create simple walking movements by holding the handles in your hand, positioning the cross of the two handles in the center of your palm. Swish the puppet gently back and forth while moving it forward across the stage.
Make your puppet run by following the walking movement, but increasing the speed and intensity of the swishing. Practice this so your puppets feet don't look too uncoordinated, unless you're trying to create a comedic scene, in which case the faster, the better.
Position the crossed bars of the control at a slight angle, so it forms an X to dance your marionette across the stage by twisting the handles side to side.
Move the arms by drawing the single panel connected to the arms by raising and lowering the corresponding end of the control. For example, to move the right arm, tug the right side of the control upward, and vice versa with the left.
Practice regularly. The more you practice these basic movements, the easier it will become for you to add personality and life to your marionettes.
