You then state that, without looking at the needle, you will thread it with as many strands of cotton as it will hold. Proceed in the following way.
Holding the needle with the point upwards beneath the table, out of sight of yourself and the others, catch one of the threads at a point between the eye of the needle and the point where they pass through each other, as in [Fig. 32], and pull that steadily downwards.

By doing this the invisible knot is passed through the eye, carrying with it two strands, and by continuing this action the knot is passed several times, until eventually a result similar to that shown in [Fig. 33] appears.
Drawing the knot to the bottom of this series of loops, you can then cut off all the ends as well as the knot, and present the threaded needle to your friends as it appears in [Fig. 33a].
