I have been looking at this idea for awhile...I love it! Have each person sign the back with a message too-take a picture as they walk in with their letter so you can make a alphabet book from Shutterfly starring family and friends!
Since you only have one room, no nurseries! Little Man Cave. What a gorgeous little boy's room. Can be "babied" then grow with the "little man."
Baby K's Bright Nursery-I love the shelves on the wall and the storage unit under the window. This will fit perfectly in my small nursery, and will add some much needed storage. The storage unit and wall-mounted book holders on the third picture down are also very nice.
