Form a bow out of the ribbon for the wrist corsage. Several strands of thin ribbon or one strand of wide ribbon work best. For the boutonniere, make a small bow out of a single strand of thin ribbon. Lay this aside to add to the flowers later. The easiest way to form a bow is to make six loops of ribbon around your hand and cut off the ends at an angle.
Slip the ribbon off the hand and, holding the loops flat, wrap another section of ribbon around the center of the loops and tie tightly. The result will look like a bow that has not yet been opened. Starting with the innermost loop of ribbon, slide it out and give the ribbon a twist to the left. Pull out the next loop and twist to the right. Continue pulling out the loops and alternating the twists until both sides of the bow loops are out. Hold the cut ends and shake the bow slightly to let it puff up. The boutonniere bow is created with a simple tie knot as though tying a shoelace.
Choose flowers to complement the school colors or the prom gown. Day lilies or calla lilies add a spectacular visual to the prom wrist corsage. Many corsages for prom use mums in the school colors. Roses make an elegantly delicate-looking prom wrist corsage.
Gather the flowers together in two groups. Make the stems an even length of about 4 or 5 inches. Use the wire cutters or scissors to cut the stems to equal lengths. Add wire to any flowers with shorter stems to make the length of the stems equal. The flower groups should be made up of three, five or seven flowers depending on how large you want the wrist corsage. The boutonniere has one or three flowers.
Lay the leaves so they are flat, with stems running from top to bottom of the work surface. This creates a base to build upon for the flowers. Add the flowers on top, just slightly lower than the top-most leaf, with the stems running in the same direction as the leaf stems. Add baby's breath for interest. The stems must all be running in the same direction.
Fasten a string of beads to the flowers, in a loop, to add more style to the corsage. This step of creating the flower sections is done twice to create two sections of flowers for the prom wrist corsage. For the boutonniere, add baby's breath behind the flower grouping.
Wrap the stems together with floral tape, starting from the top of the stems and working towards the bottom. The tape wraps at a diagonal, like the stripes on a barber pole. Make two passes with the floral tape to completely cover the stems.
Fasten the two sections of flowers together with florist wire. Slip the wrist band around the corsage so the band is laying in the middle of the two flower sections. Attach the bow to the band and the flowers, with floral wire, in the middle of the flower grouping for the wrist corsage. The bow for the boutonniere fastens at the bottom of the floral arrangement, at the top of the stem.
