I like #2 because the birds go with Cinderella theme, and I also like #3 because the design kinda looks like the pumpkin carraige, AND I like #4 because it's the beginning of the fairytale story. The first one may be a little much and would probably be a big pain to put on the wall with all the swirls, I would be affraid it would tear in a couple places. I would say they are all very adorable and any of them would be a good choice. I love your theme!
Re: Which wall decal for girl nursery?
I love 1, 2 and 4 and think all would look adorable with that bedding.
PS #2 is my bedding
