Colour
An easy way to style artworks is to choose a colour palette. It can be as simple as a group of neutrals, or you can take one specific colour from a piece.
Frame
If you want a gallery wall or shelf of prints to seem cohesive, matching their frames is an easy solution. This will make prints that are vastly different seem intentionally styled together.
Size
For an easy modern gallery wall, use artworks all the same size and line them up on your wall. This look is perfect for a hallway or stairwell.
Subject Matter
You can create a harmonious wall with all different prints if the subject matter is the same. For example a wall of modern abstracts or framed photography. Styling these prints together will look much more intentional.
