Brightly painted frames, cardboard letters and loud scrapbook paper. (or, wooden frames, cardboard letters and muted scrapbook paper, which is what I was actually planning to do on the nursery wall once the baby comes and I know initials!
Cute and simple idea for names. You could do all three names (First,middle,and last) and it not look overbearing on the wall! Or a cool idea for last name only for the living room. Or on the front of the kids bedroom door.
