Thanks for posting, robin! Yes those are the sconces I ended up using and your timing is uncanny as I was looking for the receipt for the sconces today. That's because yesterday as I was installing the back wall I broke the glass cover one of the sconces. Grrrrrrrrrrr.
Can't find the receipt but it was actually one of the things I bought locally so hopefully I can order another thru the lighting shop. They are 7 ½" wide and 12 ¼" high.
