Roost employees professional hangers/ installers!! Hanging art is sometimes as difficult as procuring it! Here are my wonderful installers giving myself and my client a good idea of how these pieces are going to look on that empty wall in her stairwell. They then marked the height of the art on the wall, we walked away, they used their magic tape measurers, and in a few minutes they were hung perfectly!! Taadaa! That is how it is done!
