Select a dozen long-stemmed calla lilies. Choose lilies that measure at least 12 inches from blossom to end. You can use fresh or silk lilies of any color scheme. Bundle the flowers together in your fist.
Arrange the flowers in your hand until the blossoms and stems are lined up evenly, meaning both ends are straight and flush. If necessary, snip about 1 inch from the ends of the stems to even the edge. Wrap a rubber band around the center of the bundled flowers to hold them in place.
Cut a length of silk ribbon measuring 24 inches in length. Squeeze a line of hot glue down the center of one side of the length of ribbon. Use a wide gauge ribbon of your choice of color.
Press the glued side of the ribbon, at one end, against the bundled stems of the calla lilies at the bottom. Firmly spiral the ribbon around the stem bundle, pulling firmly to glue the winding ribbon into place. Do this until you reach just beneath the blossoms of the calla lilies. Repeat the process by moving downward, spiraling the ribbon around the bundled stems. This will completely wrap the stems of the bouquet, accenting it with class and color.
Fold the free end of the ribbon under the straightened edge of the cut stems at the bottom. Press firmly to adhere the glued ribbon into place. Let it dry for 10 to 20 minutes.
