Pour a handful-size amount of rosin onto the floor in a corner of the dance room or off-stage. Pour it on a wood floor or in a rosin box (small, shallow wooden box).
Put on your ballet slippers or pointe shoes. Put one foot in the rosin box and rub the ball of your foot into the rosin. Take your foot out of the box and tap the rosin off on the side of the box or on the floor to remove excess rosin.
Quickly dip your heel in the rosin box. Tap your heel on the edge of the box or floor to remove excess rosin.
Rub your ball and heel into the floor to make sure your feet are sticking somewhat but not overly sticky or overly slippery.
