Wrap your slipper ribbons around your ankle firmly but not so tight as to cause discomfort. Tie them around your ankle front-to-back until you run out of ribbon.
Tie a secure knot on the inside of your ankle and tuck the knot under your ribbon so that it doesn't show.
Spray a little hairspray on the knot, and rub it in lightly with your finger.
Secure the knot under the ribbons with a needle and thread, if you want to be sure that your ballerina slipper tie won't come undone. Thread the needle through the knot and ribbons several times from several angles.
