I wanted to do a photo wall like I had seen on Pinterest.  The project turned out beautifully with these ledges.  There is a small lip to keep the photos from coming off and you can just move photos around or change them out when desired.  I would have given them a 5 star rating but one of the ledges looked like it might have been returned and was shipped without the original packaging.  They just put tape around the box and it didn't protect the shelf.  When I got it it was scraped, gouged and chipped in a number of places.  I wanted to finish the project and didn't want to take the time to return it so I just kept it and painted over it.
