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 a 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.
