If classy is what you crave, then go for a classic display scheme that's been used since Victorian times. Create a gallery wall of family photos and other small pictures in contrasting frames, arranged on a large wall such as a stairwell or hallway; this will lend a stylish elegance to your den.
This is also an excellent opportunity to make a statement about who you are by creating a wall gallery, which allows you to personalize your walls. It is recommended that at the time of beginning, lay out your framework on the floor to have a better idea of which arrangement looks the best and you can also take snapshots of the different variations and compare them to arrive at the best combination. It is important to note that not only the combination, but the placement too, is very crucial, so never hang the frames too high or too low as eye level works the best.
To add some drama to your gallery wall, pay special attention to the frames you are going to use. For example, for a neat look, frames in the same colour and size are perfect, but to add a vintage feel to your gallery, mix and match unique picture frames with an old world vibe, so that it seems that it has been collected over time.
