How to decorate with small paintings and posters 

Decorating with small paintings is simple. Besides hanging them on walls, you can also place them on benches and dressers, leaning against the wall. Dare to be creative with your posters. Challenge yourself with color and motifs – why not try something entirely new. The best thing about small posters sized 21x30 cm is how easy they are to move around. If the motif or colors don't suit one room, you can move the poster to another. 

Remember that choosing the right frame is also important. Make sure to select a frame that complements the poster's color and motif, as well as the rest of the room's decor. With small posters sized 21x30 cm, it's easy to change frames as needed.
