By putting newspapers on the cartons, several such cartons can be staggered on a wall and used as bookshelves. Of course, this means that the place is relatively large, and then you can put a small desk lamp on the tall paper box, which will have a learning atmosphere.
Don't put anything too complicated on the computer desk. If it is black, be sure to put some colorful ornaments on the computer, such as pencils with colored skins.
It's just a decoration, but it has a bright spot. The white one goes better with a simple picture frame, and nothing else is needed.
Because the bookshelf is a bit messy, the sheets must be clean, with simple totems, not too complicated, and try to match the main color of the room. If the light is good, any color will do, but if the light is not good, it is best to choose some bright and dark colors with stronger brightness.
You can put some dolls in the appropriate space. Of course, black and white is more neutral. You can put them anywhere. My son, who is loyal to Andy Lau recently, is lovely and neutral.
The above is just my personal opinion, I hope I can help you.
