Are baby girls room is in black, white, pink and gray. We purchased black picture frames from Dollar Tree and are going to put ultrasound pictures and her first pictures in them for the wall. Also...we got letters for her name and painted them to go over her crib. Another idea I saw online was to buy some cute ribbon that matches your decor, string it across the wall (like a clothes line) and use it to hang pictures from...you can change the pictures out easily!
I decorate my nursery with winnie the pooh characters.. I always love those characters..
second choice for me is under the sea creatures...
I have a friend who's husband is a tatoo artist. He's going to paint my walls w/ ladybugs and daiseys for me as a gift. If you know someone who is artistic you can do anything.
