Before I can put this topic to bed, there are a few last companies to mention; think of them as finishing touches.
First, Not Neutral has rugs that will make a little boys' room come alive. My favorite is the blue Transport 5' x 8' rug (pictured above) in wool. It's a traffic jam of cars, buses and planes--a great spot for tummy time and future car races. $500
Amy Dillard has a bevy of beautiful hand painted frames--and I know you're going to have lots of great pics to fill them. Order personalized frames or patterns like this sweet cupcake frame (right). $40
Fans of sustainable furniture will be please to know Q Collection Junior is, as they put it, using the "toughest environmental standards anywhere." They've got a full line of nursery furniture and accessories, don't miss the Stella Stackable storage (left). I love that this unit has doors to tuck away toys, books and treasures. $350 each
