If it is hand-painted, it depends on your painting skills, which is not much different from the above, but a little more difficult. There are all kinds of posters now, so they should be creative and individual, which will attract more attention.
Stage design is also divided into computer and manual.
The name of the computer is simple. Make some FLASH and add it to your stage space. If it is manual, it is a bit troublesome, but it is not difficult. As long as there are props, put them on your stage, then hang colors or curtains on the ceiling, and it is best to put some posters of you on the wall. I believe that would be good.
