In doing a little research I found out that the shape of them is known as dentil.
They seem to be used mainly in children's rooms, but I can't help to be drawn to them.
I did happen to find one version in an adult room that gives off quite the glam vibe.
Have you seen this type of valance in your inspiration files? Any images you want to share with me?
What are you feelings? Do you love it? Or can you leave it?
