Bind together wedding cards, baby shower cards, birthday cards like a scrapbook! I absolutely love this idea because I love saving cards but they just get thrown in a pile. This is such a cute idea!
Would be easy to create with a number template and left over decorative paper.
Would also make cute wallpaper for a diy bookshelf / dollhouse! DIY kids room shelving splash of color - transform plain kids shelves with scrapbooking paper, old birthday cards, anything to give a terrific backdrop for shelving.
