Please visit Project Nursery today to view my complete post on Whimsical Wallpapers:

Wallpaper is a wonderful way to may an easy design statement in a room. Long gone are the days of wallpapering every wall, why not go dramatic on one wall and leave the rest white? That way you can go a little more whimsical and bold with pattern without it being to overpowering. Plus you save some money by only wallpapering one wall.
These are a few of my favorite wallpapers to use in children's rooms:
The photo above is Frames by Graham & Brown available at Open Sky.
Frames is what you call an interactive wallpaper, meaning that children (and adults) are encouraged to write on the walls and draw inside the frames. This one is perfect for a child's room or playroom.
The whales might be my favorite. When my son moves into his big boy room in years to come, I'm hoping to put this on one of his walls.
Mavis just makes me smile. It is also interactive meaning that it can be hung in any pattern. Perfect if you are a DIY'er and want to hang the wallpaper on your own, it will allow for a margin of error!

I can just see this blackbird wallpaper on a wall behind a crib dressed in bright bedding with a little baby saying "cheep, cheep" and pointing up all the time.
Honestly I love all the wallpapers by Ferm Living but these are two of my favorites. When the patterns are bold like this they should be the focus of the room and everything else should compliment the design.
I know that we have seen this Woods wallpaper for a while (even Anthropologie carries it), but I still love the soft delicate look that it has.
Although this wallpaper is quite traditional, I really like the subtle pattern of the Beatrix Potter characters. Sweet and very baby.
