C. Borrow a wedding ring.
D. Take the handkerchief from the pocket. (The duplicate ring sewn in the corner being held preferably in the right hand.)
E. Pretend to wrap up the borrowed ring in the handkerchief, in reality wrapping up the corner ring, and secrete the borrowed ring in the right hand.
F. Take the stick from A and B and tap the folded ring with it, now being held by C. While doing so, slip the borrowed ring into the middle of the stick.
G. Hand the stick back to A and B but keep the hand on the stick over the ring.
H. Get C to cover this hand with the handkerchief, holding the ring over the middle of the stick and instruct him to let go on the word "three."
A neat little trick that can be performed by anybody who takes the trouble to practice it a couple of times.
