Displaying a collection of art doesn't necessarily mean you have to hammer a bunch of holes in your wall.  Mounting picture ledges are a great way to show off a number of framed works of art with minimal damage to your wall.  

Ledges allow you to rotate and curate your collection without committing to specific placement. They can also allow for a wider variety of frame styles without looking haphazard or sloppy. Here are some stylish gallery walls that are super easy to recreate at home.
