If you've followed Peekaboo for long you know what a fan I am of area rugs! Yes. Even on carpet. They're not only great for protecting your floor from stains, they complete the room.
I was at IKEA today and found myself utterly impressed with their selection of floor rugs...perfect for a nursery!
There were red, purple, orange and blue shags...always a hit. Then, there were the fun rugs that sparked inspiration.
This was a nice size rug (est. 4x6) for only $50!
This is a fun striped rug. I think it was a little more expensive than the first...looks like $199.00.
These round rugs are nice and soft. How cute would they be in multiples on your floor?
Here's the link to IKEA's rugs online. I advise no smaller than a 5x7 rug in a baby nursery...though a 4'x6' or a 4' round will work if it's the best you can find.

Happy rug shopping!
