A Rosette is many little circles, touching or overlapping each other. Using a pencil or your mind's eye, make a few dots on the cloth in any pattern. Each dot will be the center of a small circle.
With the thumb and forefinger pick up dot after dot and transfer to the other hand.
Wrap string or rubber bands several times around the base of all the circles which have been gathered together. Continue to wrap to the tip and back, making sure your ties are very tight.
