Line by Chiam Yu Sheng and JT Magic

Line is a novelty visual effect created by Chiam Yu Sheng from Singapore.

In this effect, a spectator selects a card and signs their name on it. The magician then loses the card in the deck. Taking another card, the magician draws a line with a marker on its back. With a flick, the line vanishes instantly. Finally, the magician spreads the deck, revealing the spectator's signed card-with the line now appearing on its back!

Line can also produce additional effects, such as transforming a curved line into a straight line. The magician draws a curved line on the back of a card and, with a flick, the curve changes into a straight line. If desired, the straight line can revert to a curved one.

Advantages:

• Highly visual and practical, perfect for performing in front of live audiences.
• Super easy to do.
