A neat and tidy room can give a slightly but chilly impression. In such a case, it is recommended to casually down the interior with a sense of omission and balance it.
For example, an art poster. It has a faint taste, loose lines with an analog feel, and art with a slightly blurred feel is perfect for such occasions.
It's a good idea to buy a book of your favorite designer, not just a poster, cut out your favorite page, frame it, and decorate it. You can always touch your favorite page, and such a trivial thing makes your daily life a little more enjoyable.
The photos and videos are cut out from my favorite art from "Marimekko Patterns and Designers (Pai International)" by Maria Harukapar and Sami Succo.
