Questions about the flashlights and curtains of the OP Annual Conference program "Light and Shadow"?

No need to bother at all. Ordinary white cloth will do. Somewhat translucent. I have tried it and it is completely fine with blackout cloth in the office. A flashlight is just a few yuan and it’s ok! To be able to present PPT images, the cloth does not need to be thick. Instead, use black as the background color when making PPT. If you don't understand something, you can ask me directly.
