Cut an additional piece of ribbon, tie it around the middle of the pile, and make a knot at what will be the bottom of the bow. Shape the loops on each side of the knot and on the loose ends of your ribbons to create the look you want. Bind the stems of the bouquet with lightweight wire.
Cover stems with floral tape if using dried flowers.
Use lightweight wire to bind each bouquet to the large guage wire, placing the flowers of each new bouquet over the stems of the last. Cover the end of the garland with decorative bow or turn the last bouquet around so that its stems are bound to the large guage wire with those of the previous bouquet.
