Select a flower that fits with the theme and color coordination of the event. Snip the stem from the flower, leaving only about one inch of stem protruding from the blossom. Flowers that make attractive quinceanera corsages include sunflowers, large daisies, and roses.
Wrap the protruding inch of stem with a 2-inch length of florist's tape. Wrap the stem several times, widthwise, until the entire stem is coated with the green, matte-textured wrap.
Cut a length of silk ribbon measuring 24 inches. Use a wide-gauge ribbon of at least 1/2 inch. Squeeze a dot of hot glue onto the center of the ribbon's surface.
Press the wrapped flower stem into the glue, making sure the flower protrudes just above the ribbon. Hold the stem in place for 10 seconds, then let the ribbon dry for 10 minutes.
Grasp each end of the silk ribbon, then tie the ribbon into a simple knot, making sure the knot is just over the center of the wrapped stem. Cut a second length of ribbon measuring about 12 inches and tie it into a simple bow. Squeeze a dot of hot glue onto the knot of the bow. Press the glued side of the bow onto the knotted ribbon of the corsage. Let the ribbon dry for 10 minutes.
Hold the corsage with the stem between your fingertips. Hold the can of spray adhesive about five inches from the surface of the flower. Press down on the nozzle to release a thin mist of glue over the surface of the flower.
Shake a handful of loose glitter over the glue-covered flower, using any colors you like. Hold the flower over a paper plate to catch the excess glitter. Let the corsage dry in your hand for two minutes before setting down the corsage.
