Hold the handkerchief in both hands; give it a twist; blow on it, and a
knot instantly appears in its centre.
Hold the handkerchief as shown in Fig. 5.

Then while in the act of blowing on it bring the hands together quickly,
throw the end _a_, held in the right hand, between the two middle
fingers of the left hand and over _b_; at the same time grasp _b_
between the two middle fingers of the right hand (Fig. 6); pull _a_
under _b_ with the left hand and _b_ under _a_ with your right, and the
knot is made. With practice you will be able to do this imperceptibly.
