Border Wallpaper-by-Numbers isn't new to the blog scene, it got a fair amount of coverage a while ago, but it is new to the MoMA Store. These whimsical and stylish 6" borders would look great in a kids room. The borders come in three different colors and pattern, and include paint by number style graphics. You can go ahead and fill them in with paints or colored pencils, or you could just leave them the way they are. $20 will get you 20 feet of 6" high border. Available from MoMAstore.
