Pull away the excess, brown or damaged foliage from around the sunflower’s head. Cut the sunflower’s stem to approximately six inches in length. Choose a sunflower bloom that isn’t oversized and fits inside your shadow box.
Cut off a six inch chunk of yarn. Tie one end of the yarn around a hanger and the other around the sunflower’s stem. Hang the sunflower in a dry, dark place for at least two to three weeks. A closet, unused room or attic is an ideal environment.
Remove the sunflower from the dry, dark space and cover the head with a light coating of hairspray. The hairspray preserves the head without discoloring the petals.
Remove the back of the shadow box and cover it with decorative items. Use wallpaper, decoupage glue and decorative paper or photographs to decorate the backing of the shadow box.
Mount the sunflower’s on the back of the shadow box with straight pin. Place a dab of hot glue on the back of the sunflower’s head and hold it against the back of the shadow box for 30 seconds.
Add more decorative elements to the shadow box, if desired. Otherwise, secure the back against the frame and display your shadow box.
