Stage shelves generally use trusses, which can be painted or covered with cloth, as well as background boards. The most primitive is gauze curtains with poles on them.

If you look like this, there will be more. The veil will be made into various radians, the LOGO of the new person will be painted, and photos will be posted on the background board. In all respects, it is good to be beautiful. Remember to coordinate colors, such as rose red, navy blue and purple. Red is hard to grasp, tacky and atmospheric. It is not recommended to use contrast color, if the color sense is not good, it will be difficult to grasp. Don't be too monotonous, it will be better to combine more points. Of course, being an alien will cost more, but not too much, depending on the budget.
