Start with What Already Feels Like You
A personal home rarely begins with a perfectly defined style. It starts with things you keep returning to: a particular colour, the shape of an old chair, a photograph, a subject that makes you curious. Choosing art prints becomes easier when you notice those preferences before trying to give the whole room a label.
Walk through the space and identify what you would keep if you were beginning again. Include practical furniture and sentimental objects, not only the pieces you consider decorative. A favourite print should have a relationship with the life already taking place around it, rather than requiring everything else to be replaced.
Make a short selection of images you enjoy, then leave it for a few days. Look again without concentrating on whether they match the curtains. Notice which ones still reward attention and which were mainly appealing because they resembled a room you saw elsewhere.
This approach leaves room for surprise. A graphic image beside a worn wooden cabinet may tell you more about your taste than a complete coordinated set. Begin with one picture you want to live with, and let the room develop around that choice at a pace that suits you.
