It was a lot of work to find the right shelf.... I wanted one that would be big enough for books or whatnot but wouldn't be huge... it also needed to go on the wall above the other stuff but I didn't want a "floating" shelf as they tend to pull out of the wall and can sometimes fall or not be able to support much weight.
Facebook to the rescue!
After lots of internet searches and some helpful advice from friends, I settled on this shelf from Ikea. If I ever fel that it isn't doing as good as possible, Aunt robin and I will add brackets to the wall and underneath.
Regardless, Daddy installed it today and I already moved your stuffed animals up there. You are amassing quite a collection!
