I think one of the most inspiring sites when I was pregnant and dreaming about Little Bean's room was Project Nursery. We didn't know where we would be living until I was almost 7 months pregnant but I started dreaming up what type of room I wanted my Little Bean to sleep in. They have a site full of inspiration and a daily blog. I still read the blog for design inspiration.
And here is my woodland nursery. We kept it simple and used varies vinyl stickies from Pottery Barn, Wallies and Graphic Spaces.
