We turned old night-light bulbs into festive ornaments, but any size will do. Just brush on glittering glue, roll the bulb in glitter, and let dry for 15 minutes. Then hot-glue a loop of metallic embroidery floss to the bulb&#39;s base. (Glittering glue with brush, $3.65 for 4 oz.; dickblick.com): Bulb Ornament, Christmas Ornament, Glitter Bulb
