Flash Silk by Sandro Loporcaro (Amazo) lets you produce a silk hanky from nowhere, with open fingers. You can produce a card fan of your hand and after having dropped, you reveal a silk hanky or a scarf that you will put on your neck. Easy to do

No glue, thread, weight, pins, magnets, or rods are connected to hanky. No cost and always repeatable, using also without sleeves. Useful for 12, 18, or 24 inch hanky.
