In magic, a silk scarf disappeared empty-handed. What happened?

There are many kinds of magic for silk scarves. Of course, the finger sleeve mentioned upstairs is the most common one.

There is also the use of skills, first hidden in the palm of your hand and then put it in your pocket or throw it out.

Another one I have seen is that there is a rubber band on the magician's belt with a clip on it. During the performance, the silk scarf is clamped with a clamp. As soon as you let go, it will be drawn back to the magician's clothes or belt.
