Brighten up your bedroom with these fun DIY letters. Add styrofoam into cardboard letters, and then stick your favorite faux flowers into the forms. You may need a little hot glue if the flowers won't stay. We used fake silk flowers so that the letters would last longer, but you can also use lightly moistened floral foam and real flowers if creating the day before a special event. Just be sure to refrigerate your blooms, and spritz with water if they start to wilt.
