cardboard bookmarks
You can use peices of cardboard from snacks, or just scraps. now glue them together to make it sturdier, and to hide any logos or color from the boxes, unless you'd like them for design. i glued three together. now you can paint the sides with any color your want as a border. next, if you can, you can make a hole at the top for any cute keychains you would like to attach. all done!
